What happens to particles when temperature lowers and rises
when cold particles are slow and have less energy. when hot particles are faster and have more energy
Where can you find carbon
found in all living thing
What is the difference between weight and mass
Weight is how much gravitational pull an object has and mass is how much matter inside an object
