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 much heat does it take to raise the temperature of a substance one degree?
The amount of heat required is called the specific sensible heat for the substance. Sensible, in this context, means something which can be sensed. This is in contrast to latent heat which is used to change the phase of a substance without a change in temperature.
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.
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 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
Why does temperature no change during energy phase change?
During a phase change, the heat transferred to a substance is used to break intermolecular forces (latent heat), and thus the temperature of the substance does not change. The opposite also occurs: heat is transferred from a substance during a phase change without a decrease in temperature as intermolecular bonds form.
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.

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".

Electronic temperature sensor?
Electronic temperature sensors are basically a transducer which convert the heat energy to equivalent voltage . they are thermocouple and also some heat sensing device are available which change their electronic parameter when temperature change those are used in vehicle and aircraft for temperature controlling and cooling.
What is used to find the specific heat capacity of a substance?
The equation for specific heat is: C = q/temp. change x mass. C is a substance's specific heat, which is a constant for every substance. q is its heat capacity in joules, temp. change is the change in temperature in degrees Celsius, and mass is in grams.
Why the temperature did not change although heat was added to it when the potential energy of the molecules increases?
Precisely because the heat energy that was added was used up elsewhere. Temperature is a kind of kinetic energy; a change of phase (like, from solid to liquid) is a kind of potential energy.Precisely because the heat energy that was added was used up elsewhere.

Where does heat energy go when temperature is not rising?
During boiling all the heat supplied to the liquid is used up in overcoming the intermolecular forces present among the molecules of the liquid. That is why the temperature of the liquid does not change.
