10. A student mixed 100.0 grams of water at 25.0 °C with 50.0 grams of water at 55.5 °C. What is the final temperature (T;) of the mixture? The specific heat of water is 4.184 J/g °C.

A coffee cup calorimeter, including that water it contains, has a heat capacity of 425 J/K, and is initially at a temperature of 23.07 C. A 16.9 gram piece of nickel metal, initially at a temperature of 4.0°C is placed in the calorimeter. The final temperature of the calorimeter and the metal is 22.74°C. What is the specific heat of nickel metal (in Jg1 K-1)? 27 O0.44 1.4 O 25 O 145

The temperature of a 15-g sample of lead metal increases from 22 °C to 37 °C upon the addition of 29.0 J of heat. The specific heat capacity of the lead is J/g-K.

10 A student heats 84.17 mL of water to 95.27°C using a hot plate. The heated water is added to a calorimeter containing 73.92 mL of cold water. The water temperature in the calorimeter rises from 2.15°C to 37.48°C. The specific heat capacity of water is 4.184 J and the density of water is g. °C 1.00 mL Assuming that heat was transferred from the hot water to the cold water and the calorimeter, determine the heat capacity of the calorimeter. J Heat capacity of calorimeter = °C
