A device called an insolation meter is used to measure the intensity of sunlight has an area of 100 cm2 and registers 6.50 W. What is the intensity in W/m2? You must show your detailed work. No credit will be given for a final answer without the supporting steps.

If you pour 0.0100 kg of 20.0ºC water onto a 1.20-kg block of ice (which is initially at −15.0ºC), what is the final temperature? You may assume that the water cools so rapidly that effects of the surroundings are negligible. You must show your detailed work. No credit will be given for a final answer without the supporting steps. R = 8.314 J/(mol.K), or 0.0821 L.atm/(mol.K) C = 4.184 J/g⋅°C (4184 J⋅kg⁻¹⋅K⁻¹)  Latent Heat Fusion =  334 kilojoules per kilogram (kJ/kg) 1 k = 1000
