Simone has a mug of hot tea at a temperature of 90°C. She sets the mug on a counter in a room with an air temperature of 30°C. What is most likely to happen to the temperature of the hot tea?(1 point)
Responses
The hot tea will transfer thermal energy into the air, and the energy transfer will continue until the tea is at room temperature.

The investigation that shows the transfer of heat energy in the absence of matter is using electromagnetic waves to investigate radiation.
The investigation that shows the transfer of heat energy in the absence of matter is using electromagnetic waves to investigate radiation. To understand how this investigation demonstrates the transfer of heat energy in the absence of matter, we need to know that electromagnetic waves are a form of energy that can travel through empty space, such as the vacuum of outer space. These waves carry energy in the form of electromagnetic radiation, including heat energy.
By using electromagnetic waves to investigate radiation, scientists can observe how heat energy is transferred without the need for any physical particles or matter to carry the heat. This is different from the other options mentioned in the responses.
The first option, "Using a current through fluid to investigate radiation," is not related to the transfer of heat energy in the absence of matter since it involves the flow of electricity through a fluid.
The third option, "Using particle movement through a solid to investigate conduction," is related to conduction, where heat energy is transferred through direct particle-to-particle contact in a solid.
The fourth option, "Using particles in space colliding to investigate conduction," is not accurate as conduction does not involve collisions between particles in space, but rather refers to heat transfer through direct contact in a solid.
Therefore, using electromagnetic waves to investigate radiation is the investigation that demonstrates the transfer of heat energy in the absence of matter.
