a/ Compute the quantity of heat released by 25.0 g of steam initially at 100.0oC, when it is cooled to 34.0°C and by 25.0 g of w
Svetach [21]

Answer:

When put into steam

Explanation:

When a certain amount of steam at boiling temperature condenses (turning into water), the amount of heat released is

Q_1 = m\lambda_v

where in this case

m = 25.0 g = 0.025 kg is the mass of steam at 100.0°C

\lambda_v=2.256\cdot 10^6 J/kg is the latent heat of vaporization of water

So,

Q_1=(0.025)(2.256\cdot 10^6)=56400 J

Instead, the amount of heat released when the water at 100.0°C is cooled down to 34.0°C is given by

Q_2=mC\Delta T

where

m = 25.0 g = 0.025 kg is the mass of water

C=4.19\cdot 10^4 J/kg K is the specific heat of water

\Delta T=100-34=66^{\circ}C is the change in temperature

Therefore,

Q_2=(0.025)(4.19\cdot 10^3)(66)=6913 J

Since Q_1>Q_2, we can say that your hand will burn more in the first case.
