Question

Two blocks of metal are separated and have different temperatures as shown.

The blcoks are then pushed together so they touch.

Which statement describes how heat flows?

Block 1

Block 2

Block 1

Block 2

60°C

25°C

A. Heat flows drom block 1 to block 2

B. Heat flows from block 2 to block 1

C. There is no heat flow

D. Heat flows back and forth from one block to another

Answer 1

A. Heat flows from block 1 to block 2

Step-by-step explanation:

Thermal or heat energy flows when objects of different temperature come in contact. Heat naturally flows from hot objects (high temperature) to cold objects (low temperature) and will keep on flowing until an equilibrium is reached.

According to this question, two blocks of metal, which are of different temperatures, are illustrated to be in contact. Block 1 is at 60°C while Block 2 is at 25°C. Block 1 is hotter than Block 2, hence, heat will flow from block 1 to block 2.
