The temperature to which it must be heated in order to fit the shaft is 73.33 ⁰C.
<h3>
Linear expansivity </h3>
The temperature to which it must be heated in order to fit the shaft is calculated as follows;
where;
- ΔT is change in temperature
- ΔL is change in length = 50.04 mm - 50 mm = 0.04 mm
- α is coefficient of linear expansion
- L is original length
ΔT = (0.04)/(50 x 15 x 10⁻⁶)
ΔT = 53.3 ⁰C
<h3>Final temperature</h3>
T₂ - T₁ = ΔT
T₂ = ΔT + T₁
where;
- T₂ is final temperature
- T₁ is initial temperature
T₂ = 53.3 + 20
T₂ = 73.33 ⁰C

Answer:
m = 9.6 g
Explanation:
Thermal energy given to helium gas at constant volume is given as
so here we have
so we have
now we know that
for oxygen gas we have
for same amount of heat we have
C)
Plasma is the most abundant state of matter in the universe and has the most kinetic energy. It can be found in all the planets of our solar system, the sun, and other stars
The factor that can have a significant influence on a planet’s surface temperature is its atmosphere.
<h3>What is the role of the atmosphere in the planet's temperature?</h3>
The atmosphere plays a fundamental role in the Earth planet's temperature because it allows the entry and out of certain types of radiation that may increase the temperature.
The role of the atmosphere in the Earth's temperature is well documented because our temperature is thick and it increases its homeostatic temperature balance.
In conclusion, the factor that alters a planet’s surface temperature is its atmosphere.
