Answer:
<em>1.2 cm</em>
Explanation:
<u>Thermal Expansion</u>
It's the tendency that materials have to change its size and/or shape under changes of temperature. It can be in one (linear), two (surface) or three (volume) dimensions.
The formula to compute the expansion of a material under a change of temperature from 
to 
is given by.
Where Lo is the initial length and 
is the linear temperature expansion coefficient, which value is specific for each material. The data provided in the problem is as follows:
Computing the expansion we have
The expansion gap should be approximately 1.2 cm

Answer:
You answered your own question, I'm confused about what you're asking for.
Answer:
The temperature change per compression stroke is 32.48°.
Explanation:
Given that,
Angular frequency = 150 rpm
Stroke = 2.00 mol
Initial temperature = 390 K
Supplied power = -7.9 kW
Rate of heat = -1.1 kW
We need to calculate the time for compressor
Using formula of compression
Put the value into the formula
We need to calculate the rate of internal energy
Using first law of thermodynamics
Put the value into the formula
We need to calculate the temperature change per compression stroke
Using formula of rate of internal energy
Put the value into the formula
Hence, The temperature change per compression stroke is 32.48°.
