What is the change in thermal energy of the water in a pond with a mass of 1000 kg and a specififc heat of 4184 kg if the water cools by 1 degree c?
The change in thermal energy (Q) of the water can be calculated using the formula Q = mcΔT, where m is the mass, c is the specific heat, and ΔT is the change in temperature. For the water in the pond, Q = 1000 kg × 4184 J/(kg·°C) × (-1 °C) = -4,184,000 J. This indicates that the thermal energy of the water decreases by 4,184,000 joules as it cools by 1 degree Celsius.

What has more thermal energy 90 degree cup of water or a 90 degree bathtub?
A 90-degree bathtub contains significantly more thermal energy than a 90-degree cup of water due to its larger volume. Thermal energy depends not only on temperature but also on the mass of the substance; since the bathtub holds substantially more water, it has a greater total energy content. Therefore, even though both are at the same temperature, the bathtub has more thermal energy overall.

What variable represents thermal energy in the equation Q equals mcT?
In the equation ( Q = mc\Delta T ), the variable ( Q ) represents thermal energy. Here, ( m ) is the mass of the substance, ( c ) is the specific heat capacity, and ( \Delta T ) is the change in temperature. The equation calculates the amount of thermal energy absorbed or released by a substance when its temperature changes.
How is temperature and thermal energy of an object related?
Temperature and thermal energy are related in that they both measure the degree of molecular motion within an object. Temperature is a measure of the average kinetic energy of the particles in an object, while thermal energy is the total kinetic energy of all the particles. A change in thermal energy will cause a change in temperature, and vice versa.
