If the temperature rises in a reaction. Exothermic is if it loses heat.
Have a nice day, brainliest would be fantastic.
The speed and wavelength changes as a waves travels to a different depth. Slower and bigger amplitudes in shallower depths. Freq does not change
Answer:
Their average kinetic energy increases
Explanation:
The average kinetic energy of the rice molecules increases as the pot is left on the cooking stove.
Heat is transferred to the pot by conduction from the heat source. The heat is then transferred to the rice in the cooking pot by convection.
- As the water in the pot heats up.
- The rice gains thermal energy.
- This causes the molecules of the rice particles to start vibrating.
- As the molecules vibrate about their fixed position, their thermal energy continues to increase.
- Therefore, the amount of heat absorbed by the rice increases with time and this actually cooks the food.
The correct answer is C) There are more particle collision
With more particle collision, more reactions are created.
Answer:
Pressure
Explanation:
Basically when you are pressing something you are applying force over an area thus Pressure is force divided by area.
