The change in temperature of a substance when heated, depends on its specific heat capacity. a. If the specific heat capacity of lead is 120 j/kgk, what is the heat energy required to raise the tempreture of 0.50 kg of a lead ball from 25°C to 45°C?   b. The 0.50 kg lead ball at 45°C is now dropped into a calorimeter with water at 20°C. if the final temperature of the ball-water system is 25°C, what is the mass of the water?
