Question

Help answer these questions please!

You only have to answer the first one unless it’s already been answered then answer the next one (if you could explain how you did it, it would be much appreciated :))

Answer 1

1a: Lead atoms are heavier than aluminum atoms, which means that a given mass of lead contains fewer atoms than the same mass of aluminum. Since the heat required to raise the temperature depends on the number of atoms, it takes less heat to raise the temperature of the lead than the temperature of the aluminum.
