What most influences the amount of energy needed to change the temperature of a substance?
The amount of energy needed to change the temperature of a substance is most influenced by its specific heat capacity, which is the amount of energy required to raise the temperature of a given mass of the substance by 1 degree Celsius. Substances with higher specific heat capacities require more energy to change temperature compared to those with lower specific heat capacities. Additionally, the mass of the substance being heated also plays a role in determining the amount of energy needed.
What does the latent heat of vaporization represent?
The amount of energy required to turn a mole of a liquid into a gas
How much energy is needed to raise the temperature 2.0 g of water 5 at degrees Celsius?
The amount of energy needed to raise the temperature of a substance is given by the equation Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. For water, the specific heat capacity is 4.18 J/g°C. Plugging the values into the equation, we get Q = (2.0 g)(4.18 J/g°C)(5°C) = 41.8 J. Therefore, 41.8 Joules of energy is needed.
What is the energy it takes to move or change something?
The energy required to move or change something is called mechanical energy. This can be in the form of kinetic energy (energy of motion) or potential energy (energy of position). The amount of energy needed depends on the mass of the object and the distance it needs to be moved or changed.
What do we call the amount of energy required to change from a liquid to a solid?
The amount of energy required to change from a liquid to a solid is called the heat of fusion. This energy is needed to disrupt the intermolecular forces holding the particles in a liquid state and rearrange them into a solid structure. It is also known as the latent heat of fusion.
What is needed to create change in a system?
The amount of energy is used to make the change.

What is the name of heat energy that changes ice into water and water into steam?
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
The amount of energy needed to change a given mass of ice to water at constant temperature is called the heat of condensation crystallization fusion formation?
The amount of energy needed to change a given mass of ice to water at constant temperature is called the heat of fusion. This is the heat energy required to change a solid to a liquid at its melting point.
What is the amount of energy needed to raise the temperature of 1kg of water by 1 degree Celsius?
phase change
What does the latent heat of vaporization represent?
The amount of energy required to turn a mole of a liquid into a gas
What do you call the amount of energy needed to change a material from the solid state to the liquid state?
either potential or kinetic
What must be strong to in order to cause a chemical change to take place?
A sufficient amount of activation energy is needed.
How much energy is needed to raise the temperature 2.0 g of water 5 at degrees Celsius?
The amount of energy needed to raise the temperature of a substance is given by the equation Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. For water, the specific heat capacity is 4.18 J/g°C. Plugging the values into the equation, we get Q = (2.0 g)(4.18 J/g°C)(5°C) = 41.8 J. Therefore, 41.8 Joules of energy is needed.
Energy needed to change material from solid to liquid?
The energy needed to change a material from solid to liquid is called the heat of fusion or melting point. This energy is required to overcome the intermolecular forces holding the solid together so that it can transition into a liquid state. The amount of energy needed varies depending on the specific material.
What is the energy it takes to move or change something?
The energy required to move or change something is called mechanical energy. This can be in the form of kinetic energy (energy of motion) or potential energy (energy of position). The amount of energy needed depends on the mass of the object and the distance it needs to be moved or changed.
The amount of useable energy decreases when?
The quality of energy decreases when you use it due to the second law of thermodynamics. Essentially, the energy spent from various reactions is processed, which reduces the amount of work needed to extract it.
