which of the following statements demonstrates radiation of heat?
a hot air balloon rises because a burner heats air which rises lifting the balloon.
chase touches the lid of a pot on the stove, burning his hand.
Mr. Smith keeps his baby chicks warm on a cold night by turning on an infrared heat lamp bulb in their coop.
Brandie burns her feet on the concrete when she gets out of pool.
The statement that demonstrates radiation of heat is:
"Mr. Smith keeps his baby chicks warm on a cold night by turning on an infrared heat lamp bulb in their coop."
Radiation of heat occurs when heat energy is transferred through electromagnetic waves, such as infrared rays, without direct contact between objects. In this statement, the heat lamp bulb emits infrared radiation, which warms up the baby chicks without physical contact.
The statement that demonstrates radiation of heat is: "Mr. Smith keeps his baby chicks warm on a cold night by turning on an infrared heat lamp bulb in their coop."
Explanation: Radiation of heat refers to the transfer of heat energy through electromagnetic waves. In this statement, Mr. Smith is using an infrared heat lamp bulb, which emits infrared radiation. The heat energy is transferred from the lamp to the baby chicks through the air without directly touching them. This is an example of radiation of heat.
