Exactly 3.0 g of carbon was burned to CO2 in a copper calorimeter. The mass of the calorimeter is 1500g, and there is 2000 g of water in the calorimeter. The initial temperature was 20°C, and the final temperature is 31 °C. Calculate the heat given off per gram of carbon. (CCu = 0.093 cal/g·°C). Neglect the small heat capacity of the carbon and carbon dioxide.

A 0.012 kg cube of ice at 0.0°C is added to 0.477 kg of soup at 81.7°C. Assuming that the soup has the same specific heat capacity as water, find the fi- nal temperature of the soup after the ice has melted. The specific heat of water is 4186 J/kg °C and water's latent heat of fu- sion is 3.33 x 105 J/kg. Answer in units of °C. Your response... Previous Responses X #1.79.7 PALETTE

A stone of mass 13 kg is dropped into a tank of water from just above the watersurface. The tank contains 100kg of water which is 1.3m deep. The stone has aspecific heat of 1000 J/kgK and water 4200 J/kgK. If the water and stone are initiallyat the same temperature, determine the temperature rise f the water. State anyassumptions made answer: 3.8x10^-4K

The American Burn Association states 3. You heat up an aluminum sphere of radius r, 1.27254 cm to 100 °C. You cool a 20.0 g copper ring to 0.00000 °C. The inner radius of the copper ring is r, 1.27000 cm. You then place the sphere on top of the ring and they are allowed to reach thermal equilibrium. Assume no heat loss to the surroundings. At the equilibrium temperature the sphere falls through the ring. (a) What is the thermal equilibrium temperature? (b) What was the amount of heat that was transferred between the ring and the sphere? (e) Which object lost the heat and which object gained the heat? (d) What is the mass of the aluminum sphere? Do not use the definition of density to solve for the mass. O
