A chemist carefully measures the amount of heat needed to raise the temperature of a 1.28kg sample of a pure substance from 11.1°C to 17.0°C. The experiment shows that 14.kJ of heat are needed. What can the chemist report for the specific heat capacity of the substance? Round your answer to 2 significant digits.

rom −5.2°C to 19.2°C. The experiment shows that 404.J of heat are needed. What can the chemist report for the specific heat capacity of the substance? Round your answer to 3 significant digits.

The specific heat capacity of a pure substance can be found by dividing the heat needed to change the temperature of a sample of the substance by the mass of the sample and by the change in temperature. The heat capacity of a certain substance has been measured to be 1.50J·g°C. Suppose 203.g of the substance are heated until the temperature of the sample has changed by 27.2°C.Write an equation that will let you calculate the heat Q that was needed for this temperature change. Your equation should contain only symbols. Be sure you define each symbol.

Calculate the amount of heat required to raise the temperature of 851.2 mL of a solution from 22.9 °C to 35.2 °C if the solution has a density of 1.04 g mL–1 and a heat capacity of 4.08 J K–1 g–1.

When 860J of heat energy is supplied to a 0.4kg of a substance, its temperature rises from 250C to 500C. What is the specific heat capacity of this substance?Question 24Answera.120J/kg kb.172 J/kg kc.86J/kg kd.43J/kg k

The equation below can be used to find the specific heat capacity of a substance. Work out the specific heat capacity of a substance if it takes 5,200J of energy to heat 2kg of it from 42°C to 47°C.
