Jasmine carried out an experiment. She placed two bowls of sand and water in the sunlight. She took the temperatures after an hour. She then took both the bowls into her home and placed them in an area with no light. She took another temperature after an hour and conducted the following observations:

	Sand	Water
Before placing the bowls in the sunlight	370C	300C
After keeping the bowls in the sunlight for one hour	370C	320C
After keeping the bowl inside the house for one hour	310C	310C
