How does the temperature of the water in the large beaker compare or contrast with the temperature of the water in the small beaker?

• The water in the large beaker and the water in the small beaker have the same temperature because the thermometers show the same reading

• The water in the small beaker has a greater temperature than the water in the large beaker because the water in the small beaker has less mass

• The water in the large beaker has a greater temperature than the water in the small beaker because the water in the large beaker has more thermal energy.

• The water in the large beaker has a greater temperature than the water in the small beaker because the water in the large beaker does not cool as quickly when heated
