A 1.5 m3 tank contains 500 kg of liquid water in equilibrium with pure water vapor, which fills the remainder of the tank. The t
emperature and pressure are 100°C and 101.33 kPa. From a water line at a constant temperature of 70°C and a constant pres- sure somewhat above 101.33 kPa, 750 kg of liquid is bled into the tank. If the temper- ature and pressure in the tank are not to change as a result of the process, how much energy as heat must be transferred to the tank?

Answer:
b. 3 times
Explanation:
Lets take
Coefficient for ordinary glass = α₁
Coefficient for pyrex glass = α₂
Given that α₁ = 3 α₂
Initial length of both glasses are equal = L
Change in the temperature is also same .= ΔT
We know that change in the length given as
ΔL = L α ΔT
Therefore
ΔL₁ = 3ΔL₂
Therefore change in the length of original glass is three time of pyrex glass.
