What else can I help you with?
What has the more heat energy at 100 degrees Celsius water or steam?
steam. It has to go through a phase change, which takes additional energy to get there.
What heats up and cools down the slowest land or air?
Land heats up and cools down the slowest. The reason for this is because it takes little energy to heat air compared to what it takes to heat land. Land has a higher heat capacity than air. That means it takes more thermal (heat) energy to raise the temperature of a volume of earth a couple of degrees than it does to raise the temperature of the same volume of air a couple of degrees. To heat land rather than air, it takes more heat energy and more time. As regards cooling, it takes more time to cool land than air because it takes more time for the heat energy to get out of the land. You've experienced "heat capacity" before. If you touch a metal handrail on a hot day, it burns a bit. There is a lot of heat in that metal handrail, and it is being transferred to your hand. And transferred, and transferred. All that heat in there wants to get into your cooler hand. The heat capacity of metal is fairly high. It holds a lot of heat. Land has a lot of heat capacity, too.
What does it mean to have a higher specific heat?
Having a higher specific heat means that a substance requires more energy to change its temperature compared to a substance with a lower specific heat. This property can help regulate temperature changes, making substances with higher specific heat more resistant to rapid temperature fluctuations.
What is the specific heat of dry air and how does it affect the temperature changes in a system?
The specific heat of dry air is approximately 1.005 kJ/kgC. This means that it takes 1.005 kilojoules of energy to raise the temperature of 1 kilogram of dry air by 1 degree Celsius. The specific heat of dry air affects temperature changes in a system by determining how much energy is needed to raise or lower the temperature of the air. Higher specific heat means it takes more energy to change the temperature, while lower specific heat means it takes less energy.
Why it takes more energy to raise the temperature of water than it does gold?
Water has a higher specific heat capacity than gold, meaning it requires more energy to raise its temperature. This is because water molecules can hold more heat energy due to their intermolecular structure compared to gold. As a result, more energy is needed to increase the kinetic energy of water molecules and raise the temperature of water.
What kind of energy does a candle take?
It takes the energy of heat.
When a chemical reaction takes in more energy than it gives off it becomes what?
When a chemical reaction takes in more energy than it gives off, it becomes an endothermic reaction. In an endothermic reaction, energy is absorbed from the surroundings in the form of heat.
What color of hair carries more stactic electricity?
The darker hair color carries more energy because it takes in more heat.
What has the more heat energy at 100 degrees Celsius water or steam?
steam. It has to go through a phase change, which takes additional energy to get there.
What energy change takes place in a kettle?
Electrical energy -> Heat energy -> Sound energy.
How does temperature affect energy?
Thermal energy is heat. More heat is more thermal energy.
Is melting a process to add heat energy to the environment?
No. It takes heat from the environment.
Why is more heat energy required to rise the temperature of water by 10C when the volume of water is greater?
More heat energy is needed to raise the temperature of a larger volume of water because a larger volume of water contains more molecules, which require more energy to vibrate and increase their kinetic energy. This results in a greater heat capacity for the larger volume of water, meaning it can absorb more heat energy without a significant increase in temperature.

A substance with a higher specific heat will take more energy to raise its temperature?
It means that it takes more energy to produce the same increase in temperature in the same amount. For example it takes more energy to raise the temperature of 1 gram of water by 1 degree than it does to do the same with 1 gram of iron. Therefore water has a higher specific heat.
Amount of energy it takes to change a material from a solid to a liquid is the heat of?
Heat of fusion.

Having a higher specific heat means that a substance requires more energy to change its temperature compared to a substance with a lower specific heat. This property can help regulate temperature changes, making substances with higher specific heat more resistant to rapid temperature fluctuations.
