Does it take less energy to heat hotter water than colder water?

Yes, as the molecules of the hot water are already in motion, they need less energy to speed up and transfer it whereas the molecules of cold water need far more energy so that they get into motion and then transfer energy.

Why does energy flow out of the house?
It is not clear what sort of energy you are talking about. In the case of heat: heat has a natural tendency to flow from hotter objects to colder objects. If your house is hotter than the surroundings, then heat energy will flow out of it.
If hot water is added to cold water and the cold water heats up what is this process called?
The process is simply heat transfer from hotter water to colder water.
Why do your feet feel colder when you get into a pool using second law of thermodynamics?
The basic principle here is that heat tends to flow from hotter objects to colder objects - in this case, from your feet to the cold water.
What energy does hot water have?
If you mean the water in the oceans, it is the sun's energy that does this. Water absorbs Kinetic Energy to 'heat up'. Therefore, any energy source that can impart Kinetic Energy to Water will heat it.
When the reactants get colder in an endothermic reaction what has happened to the heat energy?
Endothermic reaction means reactions which absorbs heat energy to carry out reaction. So if the reactants are at colder condition, process/operation require much more heat energy,ie, heat energy consumption will be more.
Does heat energy flows from colder to hotter?
No heat does not flow from colder to hotter. It flows from hot to cold.
Can heat transfer through radiation from colder to hotter body?
Yes, heat DOES transfer from the colder to the hotter body but there is a NET heat transfer from the hotter to the colder body.
The transfer of thermal energy from a hotter to a colder substance is called?
Heat transfer
Why does energy flow out of the house?
It is not clear what sort of energy you are talking about. In the case of heat: heat has a natural tendency to flow from hotter objects to colder objects. If your house is hotter than the surroundings, then heat energy will flow out of it.
Why is thermal energy so hard to store?
Heat has a tendency to move from hotter to colder substances. To store thermal energy, you need to keep an object hotter (or colder) than its surroundings; and there are no perfect insulators that stop the flow of heat altogether.
What are the examples of heat energy?
Heat energy involves the transfer of energy from a hotter body to a colder one. This can happen via radiation, conduction, or convective circulation.
What occurs when heat flows from a hotter object to a colder object?
The hotter object will get colder than it was, the colder object will get hotter than it was. Heat flow will continue until both objects are at the same temperature.
In what direction does thermal energy flow naturally?
Heat will naturally flow from hotter to colder objects.
What is heat and thermal energy?
Heat is the energy transferred from one body to another as the result of a difference in temperature. Heat flows from a hotter body to a colder body when the two bodies are brought together. This transfer of energy usually results in an increase in the temperature of the colder body and a decrease in that of the hotter body. Temperature is the measure of hotness expressed in terms of any of several arbitrary scales, such as Fahrenheit, Celsius, or Kelvin. Heat flows from a hotter body to a colder one and continues to do so until both are at the same temperature. Temperature is a measure of the average energy of the molecules of a body, whereas heat is a measure of the total amount of thermal energy in a body. Thermal energy is the internal energy of a system in thermodynamic equilibrium by virtue of its temperature. A hot body has more thermal energy than a similar cold body, but a large tub of cold water may have more thermal energy than a cup of boiling water. Thermal energy can be transferred from one body, usually hotter, to a second body, usually colder, in three ways: conduction , convection, and radiation.
What are the characteristics of heat?
Heat travels from a hotter place to a colder place.

What would be the result of removing heat energy from a cup of water?
The water will get colder.
