Question

2. A person with a body temperature of 37°C holds an ice cube with a temperature of 0°C

in a room where the air temperature is 20°C. The direction of heat flow is
a) From the person to the ice, only
b) From the person to the ice and air, and from the air to the ice
c) From the ice to the person, only
d) From the ice to the person and air, and from the air to the person

Answer 1

b) From the person to the ice, and from the air to the ice

Step-by-step explanation:

The direction of heat flow in the room is from the person to the ice and from the air to the ice.

The ice is at the lowest temperature.

• Heat flows from a place with a higher measure of heat to a place with a lower amount of heat.
• Since the ice has the lowest heat, there is a thermal gradient set up.
• Heat will flow from the body and air towards to the ice.
