Answer 1

Answer:

Brick

Explanation:

Answer 2

Answer:

Explanation:

Brick has a heat capacity of 840 J/kg degree Centigrade.

That means that if you have 1 kg of brick, you will need to add 840 joules of heat to get it to go up 1 degree C.

The heat capacity of iron is 450 J/kg (degree centigrade).

Brick has the higher heat capacity. Undefined in all of this is a joule. It is a work unit. The problem is that to define a joule accurately, you need to bring in a lot of other units. Content yourself by understanding that both the iron and the brick are measured in the same units -- Joules.
