How much energy is required to raise the temperature of 1.50kg of cadmium from 18.6°C to 168°C?
A 40 g block of ice is cooled to -70°C and is then added to580 g of water in an 80 g copper calorimeter at a temperature of25°C. Determine the final temperature of the system consisting ofthe ice, water, and calorimeter. Remember that the ice must firstwarm to 0°C, melt, and then continue warming as water. The specificheat of ice is 0.500 cal/g ·°C = 2090 J/kg°C. A 268g block of gold at 84°C is immersed in 155 gof water at 25.0°C. Find the equilibrium temperature, assuming thesystem is isolated and the heat capacity of the cup can beneglected
