How Much Cold Water Is Needed to Adjust Bath Temperature?

In summary, the conversation discusses a situation where the hot water tap was mistakenly left on while filling up a bathtub, resulting in a temperature of 60 C. The individuals then consider how much cold water at 9 C needs to be added to the tub in order to reach a final temperature of 36 C. They mention using the equation mct=-mct to solve this problem.

MODERATOR NOTE: MISPLACED HOMEWORK, SO NO TEMPLATE

When filling up the tub for a bath, only the hot water tap was turned on. After realizing the mistake after a minute with half the tub at 60 C, how much cold water (as fraction of the whole tub) at 9 C must be added such that the final temperature of the water is 36 C?

Would the solution have to do with the equation mct=-mct?

Thanks in advance!

If you fix the symbols there (are the mct on the left and right side the same thing?) and write down what they mean, you can use this formula, yes.

What is thermal energy and how is it related to temperature?

Thermal energy is a type of energy that is related to the motion of particles in a substance. It is directly proportional to the temperature of the substance, meaning that as the temperature increases, so does the thermal energy.

How is thermal energy transferred between objects?

Thermal energy can be transferred between objects through three main processes: conduction, convection, and radiation. Conduction is the transfer of thermal energy through direct contact between objects. Convection is the transfer of thermal energy through the movement of fluids, such as air or water. Radiation is the transfer of thermal energy through electromagnetic waves.

What are some examples of thermal energy?

Some examples of thermal energy include the heat from a fire, the warmth of the sun, the steam from a boiling pot of water, and the heat from a hot cup of coffee. Any object or substance with a temperature above absolute zero (0 kelvin) contains thermal energy.

How is thermal energy measured?

Thermal energy is typically measured in joules (J). However, in some cases, it may also be measured in calories (cal) or British thermal units (BTU).

Why is thermal energy important?

Thermal energy is important because it is a vital part of many everyday processes and technologies. It allows us to cook our food, heat our homes, power our cars, and generate electricity. Understanding thermal energy is also crucial for developing sustainable energy sources and combating climate change.
