The thermal motion of their particles spreads into your body. But there are different ways for that heat to transfer: It can transfer by conduction, convection, or radiation. Conduction is the transferring of heat by direct contact. Convection is transferring heat through the motions of fluids (gases and liquids).
Answer:
A harmonica.
Explanation:
The structure of a harmonica is built in such a way that when the air is blown by the player in it, the air moves within the rectangular structure and making sound vibrations. Sound is heard when an object vibrates. The movement of this vibration creates sound waves, and these waves enter our ears in the form of music.
Therefore, the instrument that will make the slowest vibration among the given instrument will be the harmonica. Thus option D is correct.

Explanation:
Answer: Independent variable: The amount of coffee grounds.
Dependent variable: The taste of the coffee.

Explanation: In an experiment the independent variable is the variable that you change, the dependent variable is the variable that you are testing to see if it will change because of the change you made, and the controlled variables are the variables that stay the same.
h, it has the lowest density so it makes sense it is the gas.
