Physics Practice: Calorimetry (Mock Test 3 - Advanced)
1. Advanced Analysis: When $1 \text{ g}$ of ice at $0^{\circ}\text{C}$ is converted into steam at $100^{\circ}\text{C}$, the total heat absorbed is approximately:
2. Land and Sea Breezes occur because of the difference in ________ of land and water.
3. Why is a burn caused by steam at $100^{\circ}\text{C}$ much more severe than a burn caused by boiling water at $100^{\circ}\text{C}$?
4. The temperature of $50 \text{ g}$ of copper (specific heat $0.4 \text{ J/g}^{\circ}\text{C}$) rises by $10^{\circ}\text{C}$ when it absorbs $Q$ amount of heat. The same amount of heat $Q$ is given to $20 \text{ g}$ of water. The rise in temperature of water is:
5. "Regelation" is the phenomenon in which ice melts under ________ and refreezes when it is removed.
6. In cold countries, water pipes often burst in winter because:
7. The average kinetic energy of molecules is a measure of:
8. A solid substance is at its melting point. On giving it more heat, its temperature ________.
9. Which has the highest specific latent heat among common substances?
10. On a winter day, why do wooden floors feel warmer than tiled floors at the same temperature?
