According to conservation of energy, if a glass of warm water cools off something else must warm up. What is it that warms up?
A. The surrounding air
B. The glass that the water is in
C. Both the air and the glass can warm up
D. Neither the air nor the glass will warm up
Homework Answers
Solution : According to the question given.
Conservation of energy states that energy neither created nor destroyed it just travels one medium to another medium.So here energy released while cooling hot water in a glass transferred to glass initially by conduction process and again that glass transfers same into surroundings by convection process.
Hence in this process glass as well as surroundings both gets heated

You place a glass beaker of water on a stand over a glass alcohol burner, and light the burner. The combustion reaction combines ethanol and oxygen to produce carbon dioxide, water, and energy. The water in the beaker starts to boil. For the physical system including the alcohol, the water, and the surrounding air (ignore the beaker, the stand, the burner etc.) what energy systems are changing? a) Ebond, ethanol, E bond, air, Ethermal, water, E thermal, air b) Ebond,...

The water level in a vertical glass tube 1.00 m long can be adjusted to any position in the tube. A tuning fork vibrating at 693 Hz is held just over the open top end of the tube, to set up a standing wave of sound in the air-filled top portion of the tube. (That air-filled top portion acts as a tube with one end closed and the other end open.) Take the speed of sound to be 343 m/s....

The glass tube inside the photocell that contains the anode and the cathode must be evacuated of all air molecules. This is done in order to prevent any potential collisions between the ejected electrons and the air molecules. What would be the result of such a collision occurring? Select one: a. The ejected electron will lose some of its kinetic energy due to a collision with an air molecule which would cause the stopping potential recorded to be higher. b....
