What else can I help you with?
Explain why this statement is true. It is only possible to make something cold by taking away its thermal energy?
When you remove thermal energy from an object, its particles slow down and the temperature decreases, making the object cold. If you add thermal energy, the particles speed up and the temperature increases, making the object hot. Cold is the absence or lower level of thermal energy, so taking away thermal energy is the only way to make something cold.
Can thermal energy be cold?
No, thermal energy cannot be cold. Thermal energy is a form of energy that is related to the temperature of an object or substance. Cold temperatures indicate a lower amount of thermal energy, while hot temperatures indicate a higher amount of thermal energy.
In which direction does thermal energy flow, from hot to cold?
Yes, thermal energy flows from hot to cold.
What is the relationship between cold and heat, and how can we define cold as the absence of heat?
Cold and heat are related in that they are both forms of thermal energy. Heat is the presence of thermal energy, while cold is the absence of heat. Cold can be defined as a lower level of thermal energy compared to heat.
Do cold things have heat?
No, cold things do not have heat. Heat is a form of energy that is transferred from hot objects to cold objects. Cold objects have less heat energy compared to hot objects.
Is it possible for an inverted energy pyramid to exsit in the cold explain why or why not?
No, it is not possible. In a particular energy pyramid, no additional energy enters the system, and energy is lost to the environment at every level.
Is it possible to replace conventional source of energy?
In the future, new sources of energy will develop. For example, it may be possible to release energy from hydrogen in water or cold fusion may even become possible. The quicker these new energy sources become possible, the quicker we can stop using fossil fuels such as coal and oil.
Would it be possible for the thermal energy in a bowl of cold water to equal the thermal energy in a bowl of hot water?
it depends on the type of bowl...
What should you remember when opening a fridge?
A fridge has cold air generated by energy in the home. Once it is opened, the energy rushes out and the fridge needs to make more cold air to replenish. To cut energy costs, the fridge should be opened and closed as soon as possible.

How you can create cold from magnets?
It is not possible to create cold directly from magnets. Magnets generate a magnetic field but do not have the ability to reduce temperature to create cold. Cold is typically achieved through the removal of heat energy using methods such as refrigeration or air conditioning.
Do both hot and cold have energy?
Yes (with the exception of absolute zero) but the energy in hot and cold is always heat energy. (Cold is defined as the absence of heat)
How do you freeze ice without cold?
It is not possible to freeze ice without cold because the process of freezing involves the removal of heat energy from a substance, causing it to solidify into ice. Without cold temperatures or a means to remove heat, it is not possible to freeze water into ice.
Can a fish have a cold?
no. it is not medically possible for a fish to have a cold!
Can a container of hot water have the same thermal energy as a container of cold water?
No, it can't have the same thermal energy. The hot water loses energy to the surroundings. Cold is an absence of energy, as energy is removed the water becomes cold.
When you hold onto a cold item your hands feel cold why does this happen?
because the cold energy is moving toward the warm energy and the cold is taking over.
Can thermal energy be cold?
No, thermal energy cannot be cold. Thermal energy is a form of energy that is related to the temperature of an object or substance. Cold temperatures indicate a lower amount of thermal energy, while hot temperatures indicate a higher amount of thermal energy.
