What is physics?

An unknown substance has a mass of 0.125 kg and an initialtemperature of 96.9°C. The substance is then dropped into acalorimeter made of aluminum containing 0.285 kg of water initiallyat 25.9°C. The mass of the aluminum container is 0.150 kg, and thetemperature of the calorimeter increases to a final equilibriumtemperature of 32.0°C. Assuming no thermal energy is transferred tothe environment, calculate the specific heat of the unknownsubstance.
998.57 J/kg·°C

A 215-g sample of a substance is heated to 330°C and then plunged into a 105-g aluminum calorimeter cup containing 165 g of water and a 17-g glass thermometer at 12.5°C. The final temperature is 35.0°C. What is the specific heat of the substance? (Assume no water boils away.)

a piece of substance of mass 0.3kg is heated to 110ºC and then putinto 0.3kg of water at 30ºC. if the temperature of the mixture is40ºC, find the specific heat of a substance?

What is the specific latent heat of a substance having a mass of 10 kg and released an energy of 270000 KJ?
