Which of the following would have more thermal energy? 200 mL of water at 100 degreesC or 100 mL of water at 100degreesC
To determine which of the two options has more thermal energy, we need to consider the amount of water and its temperature.
Thermal energy is directly related to both the mass of the substance and its temperature.
In this case, we have two different volumes of water but at the same temperature.
To compare the thermal energy, we need to calculate the product of mass (volume) and temperature.
Let's calculate the thermal energy for each option:
Option 1: 200 mL of water at 100 degrees Celsius
- Mass: The density of water is approximately 1 gram per milliliter. Therefore, the mass of 200 mL of water is 200 grams.
- Temperature: 100 degrees Celsius.
- Thermal Energy: Mass x Temperature = 200 grams x 100 degrees Celsius = 20,000 calories (or 20,000 joules).
Option 2: 100 mL of water at 100 degrees Celsius
- Mass: The density of water is approximately 1 gram per milliliter. Therefore, the mass of 100 mL of water is 100 grams.
- Temperature: 100 degrees Celsius.
- Thermal Energy: Mass x Temperature = 100 grams x 100 degrees Celsius = 10,000 calories (or 10,000 joules).
By comparing the thermal energies, we can see that 200 mL of water at 100 degrees Celsius has more thermal energy (20,000 calories) compared to 100 mL of water at the same temperature (10,000 calories).
