Question

When you take a block of butter out of the fridge,it is hard.however,after 15 minutes at room temperature it is soft enough to spread.use kinetic theory to explain the above observation

Answer 1

You should expand on this but basically the heat from the room gives energy to the molecules, they move faster and faster with increasing heat and at some point in time the molecules begin to slip and slide over and around each other and it becomes soft enough to spread.

Answer 2

The heat from the room gives energy to the particles of the butter,they move faster with increasing heat and at some point in time,the particles begin to slip and slide over and around each other and the butter becomes soft enough to spread.

Answer 3

it gets soft

Answer 4

bad answers

Answer 5

Good answer
