Calculate the heat in kcal if a medium pancake produces enough energy to heat 2500. grams of water from 20.0 degrees Celsius degrees to 54.5 degrees Celsius. Specific heat of water is 1.00 cal/ (g * degrees C) or 4.184 J/(g * degrees C) Limited to 3 sig figs due to temperatures. Don't forget units and sig figs.

1. When 13,140 J of heat is removed from 75 grams of metal, the temperature changes from 400. K to 200. K.  What is the specific heat capacity of the metal?  Show your work and be sure to include the units. You will earn one bonus point for expressing your answer with proper significant digits. 2. A beaker contains 25 g of liquid at 15 C. The specific heat of the liquid is 2.56 Jg °CJg °C. If the liquid absorbs 704 J of heat, what is the final temperature of the liquid? Show your work

A 113.9 g piece of copper (specific heat 0.38 J/g･°C) is heated and then placed into 400.0 g of water initially at 20.7°C. The water increases in temperature to 22.2°C. What is the initial temperature of the copper? (The specific heat of water is 4.18 J/g･°C).

A sample of 0.750 g of peanut butter was burned in a coffee cup calorimeter filled with 300.0 g of water. The heat released caused the temperature of the water to increase 14.6°C. Note: heat capacity, C, of the water is 1.00 cal/g･°C. Calculate the caloric content of the peanut butter in nutritional calories per gram. Remember a nutritional calorie (C) is 1 kcal.

The specific heat of a certain type of cooking oil is 1.75 J/(g.°C). How much heat energy is needed to raise the temperature of 2.14 kg of this oil from 23 °C to 191 °C? q = J
