Item RG063003: When a light shines on the water in a fishtank, the water in the fish bowl will get a little warmer although it may be hard to notice.
A person shines a light directly on to a fish bowl so that he can see the fish better. The fish bowl and the water start out at the same temperature as the air in the room.
What will happen to the temperature of the water in the fish bowl as the light shines on it?
- The water in the fish bowl will get a little warmer although it may be hard to notice.
- The water in the fish bowl will get a little cooler although it may be hard to notice.
- The water in the fish bowl will stay the same. It will not get warmer or cooler.
- Whether the water gets a little warmer, a little cooler, or stays the same depends on how cold the water is before the lamp is turned on.
