Which of the following cases (if any) requires the GREATEST amount of heat? In each case, the material is the same. 2.00 kg of the material is to be heated by 1.5 C. 0.50 kg of the material is to be heated by 10.0 C. 1.50 kg of the material is to be heated by 3.0 C. 1.00 kg of the material is to be heated by 7.5 C.

The temperature of a 5.00-kg lead brick is increased by 525 C°. If the specific heat capacity of lead is 128 J/(kg.C°), what is the increase in the mass of the lead brick when it has reached its final temperature? O 5.80 × 10- -11 kg O 9.12 × 10-11 kg O 1.60 × 10-12 kg O 3.73 × 10-12 kg O 2.80 × 10-12 kg

On a warm afternoon (26°C), James is making fruit punch while the ice is melting (0°C) in a bowl. Assume that the specific heat capacity of the punch is 2.7 x 103 J kg-1°C-1 and of water is 4.2 x 103 J kg-1°C-1. The latent heat of fusion of water is 3.34 x 105 J kg-1. I. Michelle, a friend of James, likes her punch served ice cold, at O°C. What is the minimum mass ice cube she should select to cool her 60-gram punch from 26°C to 0°C? II. James prefers his 60-gram punch served at little warmer. What temperature will the drink be if he places a 6 g ice cube into his punch? III. Sanya, another friend, decides she wants a cup of tea. She uses 2000 W mains operated kettle filled with 1.20 kg of water at room temperature (26°C). How long will she have to wait for the water to reach boiling point (100°C)?
