Use the following information to answer question 1. A group of students is asked to design and construct a device to heat 200 g of water using either tin or aluminium. To test the two metals, they start by heating equal masses of each metal using a natural gas burner for a period of 5 min. 1. The type of variable that the different metals represent is the amounts of natural gas are burned to heat the metals, the metal that will reach the higher When equal i ii temperature is The statements above are completed by the information in row i Row A. responding variable B. responding variable C. manipulated variable D. manipulated variable ii aluminium tin aluminium tin Use the following information to answer numerical-response question 1. A coffee company sells self-heating cans of coffee, which may be convenient for people who have no access to a heat source. The heating system in the can increases the temperature of 225 mL of coffee by 40.0 °C. Assume that the specific heat capacity and density of coffee are the same as those of water. Numerical Response 1. The energy absorbed by the coffee is kJ. (Record your three-digit answer in the numerical-response section on the answer sheet.)
