The correct statement that explains why the room starts to feel cooler when the window is opened is: Cold air is moving into the room from outside.

When the window is opened, the cold air from outside enters the room, replacing the warmer air inside. This influx of cold air lowers the overall temperature in the room, making it feel cooler.

A student takes the temperature of a bottle of liquid water and a tub filled with ice. The student then places the bottle of liquid water into the tub of ice. After 15 minutes, which of the follow best describes what happens to the temperature of each? (1 point) Responses The temperature of the ice increases, while the temperature of the water decreases The temperature of the ice increases, while the temperature of the water decreases The temperature of both the ice and water decrease. The temperature of both the ice and water decrease. Both the bottle and the ice stay the same temperature Both the bottle and the ice stay the same temperature The temperature of the ice decreases, while the temperature of the water increases The temperature of the ice decreases, while the temperature of the water increases

The best response is: The temperature of the ice increases, while the temperature of the water decreases.

When the bottle of liquid water is placed into the tub of ice, heat transfer occurs. The warmer water loses heat to the colder ice, causing the water's temperature to decrease. Simultaneously, the ice absorbs heat from the water, which leads to an increase in the temperature of the ice (and might lead to some of the ice melting).
