A two-liter pot of tea at 85°C has _____ than a one-liter pot of tea at 85°C.
more thermal energy
more heat
faster-moving particles
a higher temperature
Twice as many molecules bouncing around at 85 degrees means more thermal energy.
A two-liter pot of tea at 85°C has more thermal energy than a one-liter pot of tea at 85°C.
To determine which statement is true, let's break it down:
1. More thermal energy: Thermal energy is the total energy of all the particles in an object. It depends on the temperature, size, and number of particles. In this case, both the two-liter pot and the one-liter pot of tea are at the same temperature (85°C), so they have the same amount of thermal energy. Therefore, this statement is not correct.
2. More heat: Heat is the transfer of thermal energy. In this scenario, we know that both pots are at the same temperature, so there is no heat transfer occurring between the two pots. Therefore, this statement is not correct.
3. Faster-moving particles: Temperature is a measure of the average kinetic energy (movement) of the particles in a substance. Since both pots are at the same temperature (85°C), the average kinetic energy of the particles in both pots is the same. Therefore, this statement is not correct.
4. A higher temperature: This statement is correct. The two-liter pot of tea at 85°C has a higher temperature than the one-liter pot of tea at 85°C. Temperature is a measure of the average kinetic energy of the particles, and it represents the intensity of heat. In this case, the two-liter pot contains more tea, which means it has more heat capacity and takes longer to cool down compared to the one-liter pot.
In summary, the correct statement is that the two-liter pot of tea at 85°C has a higher temperature than the one-liter pot of tea at 85°C.
