Which of the below statements are true? A. There can be a change in heat (kJ) without the temperature changing by. Heat remains constant through a change of state c. Temperature changes through a change of state d. Heat and temperature are the same

A. There can be a change in heat (kJ) without the temperature changing by.

Explanation:

A. There can be a change in heat (kJ) without the temperature changing by.

This is correct. It is what happens whenever there is a change in state.

B. Heat remains constant through a change of state

This is incorrect. During change of state like boiling, the amount of heat changes.

c. Temperature changes through a change of state

This is incorrect. During boiling, the temperature is fixed at 100 celcius

d. Heat and temperature are the same

This is incorrect. Heat refers to the total energy of the molecule. Temperature on the other hand is a measure of how hot or cold something is.  Plus they have different units.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
