In an experiment, 26.5 g of metal was heated to 98.0°C and then quickly transferred to 150.0 g of water in a calorimeter. The initial temperature of the water was 22.5°C, and the final temperature after the addition of the metal was 32.5°C. Assume the calorimeter behaves ideally and does not absorb or release heat.

An 80.0g sample of metal, initially at 96 degrees C, is placed into 150g of water initially at 26 degrees C in a calorimeter.  The final temperature of the water is 28.1 degrees C.  What is the specific heat of the metal?

A 35.0 gram object has a specific heat of 0.832 Joules/gram °C. It gained 2095 Joules of heat from the surroundings. If it had started at 25.0 °C, what was the temperature of the object after it gained the heat from the surroundings? O 25.0 degrees Celsius O 3640 degrees Celsius O 71.9 degrees Celsius O 196.9 degrees Celsius O 1.74 degrees Celsius O 53.1 degrees Celsius O 96.9 degrees Celsius

The universe contains 253 kJ less energy none of the answer choices given The surroundings must lose 253 kJ of energy The surroundings must gain 253 kJ of energy O The universe contains 253 kJ more energy

A metal sample weighing 124.00 grams and at a temperature of 95.5 degrees Celsius was placed in 48.00 grams of water in a calorimeter at 20.3 degrees Celsius. At equilibrium the temperature of the water and metal was 38.3 degrees Celsius.  What is the change in temperature of the metal?
