Julian put a heater of known power into a block of copper and recorded the temperature of the block every minute for ten minutes. His results are below. True or false? If he plots a graph of the temperature versus energy transferred, the slope of the gradient is the specific heat capacity of copper.

Look at the image below. Julian puts a heater in a block of copper and records the temperature of the block every minute for ten minutes. He multiplies the power of the heater by the amount of time that it has been on. What is he calculating?

Look at the apparatus below. Julian is finding the specific heat capacity of a block of copper. Once he turns on the power supply to the heater, which of the following will start to change?

Julian put a heater into a block of copper and recorded the temperature of the block every minute for ten minutes. His results are below. In order to calculate the amount of energy transferred, he multiplied the time in seconds by the __________ of the heater. What word completes the sentence?

Look at the apparatus below. Julian is finding the specific heat capacity of a block of copper. He will be able to calculate the __________ of the heater using the current in the heater and the potential difference across the heater. What word completes the sentence?

A researcher is heating a metal. He heats the metal so that the temperature of the metal rises at a constant rate. After 30 minutes of heating, the metal is 446°C. After 50 minutes, the metal is 726°C.(a)Choose the statement that best describes how the time and the temperature of the metal are related. Then fill in the blank.As time increases, the temperature of the metal decreases.Thetemperatureofthemetaldecreasesatarateof°Cperminute. As time increases, the temperature of the metal increases.Thetemperatureofthemetalincreasesatarateof°Cperminute. (b)What was the temperature of the metal when the researcher started heating it?°C
