7. How much thermal energy do you need to raise 1.0 kg of water at room temperature 35 °C to boiling? The specific heat of water is 4190 J/kg-K. * A. 136 kilojoules B. 272 kilojoules C. 54 kilojoules D. 1416 kilojoules O E. 4190 kilojoules
4. Wind chill describes the additional cooling that occurs when skin is exposed to wind. The equation is W(v)=-0.17v³+18.4v²-584v-239 for 0 ≤ v ≤ 45, where v is the wind speed in metres per second. The units for W are megajoules per square metres per hour. Determine the speed of the wind that gives a minimum wind-chill factor.
4. Heat up the water to 100°C and the iron to 160°C. Then, put the iron in the boiling water. What happens to their temperature eventually? The iron which had the higher temperature goes down quickly to same temperature as the water and achieved a thermal equilibrium at 100°C. In real situation the water will evaporate faster as it quickly cools down the iron as because the water already achieved its boiling point. 5. Define what thermal equilibrium is and explain its connection to question No. 4.
