Why does the temperature remains constant during the change of state?
During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
How do solids and liquids change state?
they change their state by absorbing heat known as latent heat. There is no temperature change in a substance she they change their state because the heat is used to break the intermolecular bonds between the molecule.
How is heat measured in a calorimeter?
Heat is measured in a calorimeter by monitoring the temperature change that occurs when a substance undergoes a chemical reaction or physical process within the calorimeter. This change in temperature is used to calculate the heat transfer associated with the reaction or process.
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
What tool is used to measure when a liquid becomes a solid?
Eyes and sense of touch,Ice pick.A More Technical Perspective:In a laboratory setting the change of state between a liquid and a solid is marked by a loss of heat energy while the temperature of the material remains the same. This is due to the energy surrendered by the material as its molecules take on a more "energy economic" configuration. As a consequence the devices need would be a thermometer to measure temperature change and a calorimeter to measure the rate of heat loss.Alternately the freezing point could be determined by plotting temperature change (with a thermometer) with time in a constant temperature bath. The freezing point would be marked by a flat section in the graph as heat was released by crystallization rather than heat lost due to heat capacity.
What is the heat capacity equation and how is it used to calculate the amount of heat required to change the temperature of a substance?
The heat capacity equation is Q mcT, where Q represents the amount of heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and T is the change in temperature. This equation is used to calculate the amount of heat required to change the temperature of a substance by multiplying the mass, specific heat capacity, and temperature change.
Why does the temperature remains constant during the change of state?
During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
Q equals mass x specific heat x difference in temperature?
This formula relates heat (Q) with mass, specific heat, and temperature change. It is typically used to calculate the amount of heat energy gained or lost during a temperature change in a system. The formula shows that the heat exchanged is directly proportional to the mass of the substance, its specific heat capacity, and the temperature change.
What can specific heat be used to measure change in?
Specific heat can be used to measure changes in thermal energy by using the equation: Change in thermal energy = mass x Change in temperature x specific heat
What are the factors considered for heat load calculation?
Which of the following variables are used to calculate the sensible heat load of a product? Group of answer choices Respiration heat, specific heat, and temperature change. Latent heat, product weight, and temperature change. Latent heat, product weight, and respiration heat. Product weight, specific heat, and temperature change.
How do solids and liquids change state?
they change their state by absorbing heat known as latent heat. There is no temperature change in a substance she they change their state because the heat is used to break the intermolecular bonds between the molecule.
Why temperature does not rise even if water is heated as its boiling point?
In this first heat boil the water at its boiling point that is 100 degree Celsius, when the temperature is reached then heat supplied to water not boils the water it is used to change the state of the matter means heat is used to overcome the forces of attraction to change its state and the heat is latent heat of vaporisation.so this is latent heat (hidden heat) which not increase the temperature for some time.
Why does the temperature of water does not change as it melts from solid to liquid water?
The energy that goes into temperature change is being used to change the state of the water, and until the transition is complete, it will not change temperature. The same goes for turning liquid water into a vapor. It is called the "latent heat", and sometimes "heat of fusion".
What is the formula for the change in thermal energy and how is it used to calculate the amount of heat transferred in a system?
The formula for the change in thermal energy is Q mcT, where Q represents the amount of heat transferred, m is the mass of the substance, c is the specific heat capacity of the substance, and T is the change in temperature. This formula is used to calculate the amount of heat transferred in a system by multiplying the mass of the substance by the specific heat capacity and the change in temperature.
How is heat measured in a calorimeter?
Heat is measured in a calorimeter by monitoring the temperature change that occurs when a substance undergoes a chemical reaction or physical process within the calorimeter. This change in temperature is used to calculate the heat transfer associated with the reaction or process.
How do you calculate the heat of neutralization for a chemical reaction?
The heat of neutralization for a chemical reaction can be calculated by measuring the temperature change that occurs when an acid and a base react to form water and a salt. This change in temperature is then used in the formula Q mcT, where Q is the heat energy, m is the mass of the solution, c is the specific heat capacity of the solution, and T is the temperature change.
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
