The energy required to melt one gram of a substance is known as what?
The energy required to melt one gram of a substance is known as the heat of fusion.
What does the specific heat of a substance?
The ability of a substance to hold heat.
Is heat is the measurement of energy from all particles that are in a substance?
Heat is the transfer of energy between particles due to a temperature difference. It is not a measurement of energy but rather a form of energy transfer. The total heat content of a substance is known as its internal energy.
What does specific heat of a substance represent?
The ability of a substance to hold heat.
What does the specific heat of a substance relate to temperature change?
The specific heat of a substance is the amount of heat required to raise the temperature of one unit of mass of the substance by one degree Celsius. A substance with a high specific heat will require more heat to increase its temperature compared to a substance with a lower specific heat.
The energy required to melt one gram of a substance is known as what?
The energy required to melt one gram of a substance is known as the heat of fusion.
What amount of heat needed to increase the temperature of a 1-kilogram substance by 1 and degC is known as the?
The amount of heat needed to increase the temperature of a 1-kilogram substance by 1 degree Celsius is known as the specific heat capacity of the substance. It is a measure of how much heat energy is required to raise the temperature of a given mass of the substance by one degree Celsius.
What is the direct transfer of heat from one substance to a another substance that is Touching?
It is known as: conduction.
Which insulation holds the heat the best?
Glass traps solar heat. Greenhouses are made of glass so they absorb heat for the plants.
When heat is transferred to a substance describe why the temperature goes up?
The best answer is: Because heat has been transferred to the substance, and it now contains more of it.
What is the formula for calculating the heat energy transferred when the specific heat capacity and the change in temperature of a substance are known?
The formula for calculating the heat energy transferred is Q mcT, where Q represents the heat energy transferred, m is the mass of the substance, c is the specific heat capacity of the substance, and T is the change in temperature of the substance.
What is the heat required to change the temperature of 1 gram of a substance?
The heat required to change the temperature of 1 gram of a substance is known as the specific heat capacity of that substance. It is the amount of heat energy needed to raise the temperature of 1 gram of the substance by 1 degree Celsius.
Did mount of heat needed to melt 1 kg of a substance?
The amount of heat needed to melt 1 kg of a substance, known as the latent heat of fusion, varies depending on the substance. It is typically measured in joules per kilogram (J/kg).
What material holds heat the longest and why?
The material that holds heat the longest is typically a substance with high thermal conductivity and specific heat capacity, such as metals like copper or aluminum. These materials can absorb and retain heat energy for a longer period of time due to their ability to conduct and store thermal energy efficiently.
If a substance conducts heat easily it is considered to be a?
If a substance conducts heat easily, it is considered to be a good conductor of heat. Materials like metals, such as copper and aluminum, are known for their high thermal conductivity, allowing heat to flow through them quickly.
How can one determine the heat capacity of a calorimeter?
To determine the heat capacity of a calorimeter, one can perform a calibration experiment using a known heat source, such as a substance with a known heat capacity. By measuring the temperature change in the calorimeter when the known heat source is added, the heat capacity of the calorimeter can be calculated using the formula Q mcT, where Q is the heat energy transferred, m is the mass of the substance, c is the specific heat capacity, and T is the temperature change.
What does it mean one substance is known to be a better conductor of heat than another?
If one substance is known to be a better conductor of heat than another, it means that it can transfer heat more easily and quickly through its structure. This is typically due to the substance's arrangement of atoms and electrons, which allows heat to flow more efficiently compared to the other substance.
