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.
Answer:
Plants love C02 because they like to breathe it
Explanation:
oxygen -17 and oxygen-18 are isotopes of oxygen
<em><u>Explanation</u></em>
Isotope is two or more forms of the same element that has equal amount of proton but different number of neutrons in the nuclei.
oxygen -17 and oxygen-18 are isotope of oxygen since they have the equal amount of protons but different number of neutrons in their nuclei.
that is oxygen 17 has 8 protons and 9 neutrons while oxygen 18 has 8 protons and 10 neutrons.
