Question

Explain what happens to the heat energy transferred to the water and steam mixture if the temperature does not rise while the water is boiling, Hovw the internal energy of the water and steam mixture change during this process? Does it increase, decrease, or remain the same? Explain 7. 8. Suppose you start with 250g of ice at 0°C. Calculate the amount of heat energy that must be transferred to convert the ice to steam at 100°C. Show your calculations. [Use 334 x 10 J/kg (334 J/g) for the latent heat of fusion 2.26 × 10 J/kg (2260 J/g) for the latent heat of vaporization, and 4190 J/kg (419 J/g°C) for the specific heat of water.] 9. Gas is in a cylinder sealed with a piston. If you push down quickly on the Pston and compress the gas, is work done on or by the gas? What hap to the intermal energy of the gas? What happens to the temperature of the gas? REALTIME PHYSICS: HEAT AND THERMODYNAMIC

Explanation / Answer

Now, when no external heat energy is supplied, then the ice starts melting by absorbing heat energy from the water. Ice changes completely into water at constant temperature.

At this condition intenral energy of ice increases and the internal energy of water decreases.

If the external heat energy is supplied, and the temperature is maintained constantthen the supplied heat is absorbed by both water and ice. Their internal energy increases and the energy is the thermal potential energy
