Mara has a glass beaker of water with a thermometer in it. She lets it sit on her laboratory bench top for 40 minutes. At time t=0 minutes, the thermometer reads 17 degrees C. At time t=40 minutes, the thermometer reads 25 degrees C. Which statement correctly explains the cause of the temperature increase?

• The temperature of the water increased because it transferred energy to the surround air.

• The temperature of the water increased because the surrounding air transferred thermal energy to the water.

• The temperature of the water increased because the thermal energy of the water and air were equivalent.

• The temperature of the water increased because glass is a thermal insulator.
