a manufacturer of air compressors claims that the lifetime of their compressors under typical use has a mean life of 60 monthswith a standard deviation of 4 months, but the comparable air compressors from the competing manufacturer has a mean life of55 months with a standard deviation of 10 months. suppose we randomly select 64 compressors from this manufacturer and 80
The null hypothesis for this comparison is that the two manufacturers have the same mean lifetime for their compressors.
What is compressor?
A compressor is indeed a mechanical device that lowers a gas's volume while raising its pressure. One particular kind of gas compressor is an air compressor. Pumps and compressors share characteristics in that both raise the pressure on a fluid and can move it through a pipe. The primary difference is that a compressor works to change a fluid's density or volume, which is typically only possible with gases. Compressors are frequently used for gases because liquids cannot be compressed as much as gases can. A pump's primary function is to pressurise and move liquids. To increase discharge pressure, many compressors can be staged, which involves repeatedly compressing the fluid in small steps or stages.
To test this hypothesis, we can use a two-sample t-test. Assuming that the two samples are independent and normally distributed, the test will yield a p-value. If the p-value is less than 0.05, then we can reject the null hypothesis and conclude that the two manufacturers have different mean lifetimes for their compressors.

Sketch curves representing the variation of the molar Gibbs free energy with temperature at the pressure corresponding to a triple point for an element. Repeat this sketch for a pressure slightly above and slightly below the triple point. Also draw the curves at 100 atm and compare.
J .Willard Gibbs created a new function that is now known as the Gibbs potential or Gibbs energy change (G). Pressure and temperature fluctuations have no effect on this function.
The Gibbs energy change of a system depends only on its current state, not on how it got there.
At constant pressure and temperature, a thermodynamic system can perform its maximum (or reversible) amount of work, which is referred to as Gibbs energy. In terms of thermodynamics, reversible work refers to a unique technique that ensures the system is in complete equilibrium with its surroundings.If both the extensive properties (U, G, and A) and the intensive properties (temperature and pressure) are constant, a thermodynamic system is said to be in equilibrium. Or there is no change overall in any of the properties. According to the following equation, the system is said to be at equilibrium if the reaction is reversible and the Gibbs free energy is zero.
A + B ⇄ C + D
ΔrG = 0
It is also known as the Gibbs energy for a reaction in its standard state.
0 = ΔrG + RT in K
ΔrG = - RT in K
or
ΔrG = - 2.303RT in K
ΔrG = ΔrH - TΔrS = - RT in K
For endothermic reactions, the value of ΔrH should be high and positive; if K is less than 1, little of the product is expected to form. The value of ΔrH is big and negative in the case of an exothermic reaction, and even the value of ΔrG is likely to be large and negative. When this occurs, the value of K will be significantly more than 1. Strong exothermic processes will supposedly have a higher value of K. Kilo Joule, which is frequently denoted as kJ/mol, is the unit used to measure Gibbs free energy.

calculate the final temperature after 25.0g of chromium at 54.5 c is place in 215g of water at 14.6 c. assume no heat is lost to the surroundings
215 grams of water are added to a mixture of 25.0 grams of chromium at a final temperature of 14.6 degrees Celsius. 15.1°C is the temperature if no heat is lost to the environment.
According to principle of calorimetry, heat lost by one system is equal to heat gained by another system.
eat change = m*C*∆T
Where, m is mass of system, C is specific heat and ∆T is temperature change.
Let the final temperature be T °C
Heat lost by chromium = -(25.0 g)*(0.45 J/ g °C)* ((T-54.5)°C) = -{11.25 *(T-54.5)} J
Heat gained by water = (215 g)*(4.184 J/ g °C)*((T-14.6 )°C) = {899.56*(T-14.6)} J
Heat lost by chromium = Heat gain by water
-{11.25*(T-54.5)} = 899.56*(T-14.6)

while surfaces in touch pass relative to every other, the friction between the 2 surfaces converts kinetic strength into thermal energy (this is, it converts paintings to warmth). This belongings may have dramatic results, as illustrated through using friction created by rubbing pieces of wooden together to start a fireplace.

The moment of linear momentum is the angular momentum.
Since L = m v r, the angular momentum
The particle moving uniformly round has an angular momentum that is not zero. However, because the torque is in the radial direction, the angular momentum of the particle moving in a circular motion is still conserved around the axis of rotation. Thus, the change in angular momentum can be regarded as zero.
When an object's mass (m) and velocity (v) are multiplied, the result is linear momentum (p): p = m*v. The definition of angular momentum (L), with some simplification, is the object's distance from the rotational axis multiplied by the linear momentum: L = mvr.

Equal volumes of propane, C3H8, and carbon monoxide at the same temperature and pressure have the same: 1. Density 2. number of molecules 3. number of atoms A. 1 only B. 2 only C. 3 only D. 1 and 2 only E. 1, 2 and 3 only
In this statement of propane molecules answer is E - 1,2 and 3 only.
What is propane?
propane and carbon are the monoxide have differentions properties. They do not have- the same density or the ability to combust. And Propane has 11 atoms per the molecule and carbon to monoxide has only two.
Sol-Robert Rose hypothesis says that all gases will have the same number of molecules under the same conditions. Alejandro said that if all gases have the same volumes, they should have the same number of Molecules or moles. Boulding was directly proportional to the number of moles and the volume was proportional to the evolve mole.

how much work must the spacecraft engines perform to move the spacecraft to a circular orbit that is 3500 km above the surface?
To solve this problem, we need the concepts of the virial theorem and the work energy theorem:
First, calculate the radial distance of the spacecraft in both the initial and final states. We use the virial theorem to calculate the total spacecraft energy in both the initial and final states. Finally, use the work energy law formula to calculate the work done by the plane.
The expression of total energy is written as,
E = -1/2 (GMm/r)
Work done, W = (-1.4477 ×[tex]10^{10}[/tex]J) - (-1.9879 ×[tex]10^{10}[/tex]J)
= 5402.0×[tex]10^{6}[/tex]J
Therefore, The amount of the work done by the spacecraft is:
5402.0×[tex]10^{6}[/tex]J
What is work done?
Every time a force moves something far away, work is done. Energy transferred or work done can be calculated by multiplying the force by the distance traveled in the direction of the force.
