A student measures the temperature of a 0.2 kg block of platinum and the change in its internal energy as it is heated. The results are shown in the graph. Use the values in the graph to calculate the specific heat capacity of platinum. Give your answer to 3 significant figures.
A cube of copper with sides of length 5 cm, is heated by , taking 431.2 J of energy. Find the density of copper. Use a value of for the specific heat capacity of copper. Give your answer to 3 significant figures.
The graph shows the change in the internal energy against the change in the temperature for three 0.1 kg blocks of metal. The orange line represents a block of tungsten, the green line represents a block of iron, and the blue line represents a block of nickel.
Which of the 3 metals has the highest specific heat capacity?
Which of the 3 metals has the lowest specific heat capacity?
If all 3 metal blocks start at and J of heat is transferred to each block, which blocks will be hotter than ?
