Why does temperature remain constant when wax solidifies?
Temperature remains constant during the solidification of wax because the heat energy released by the wax as it solidifies is absorbed by its surroundings. This is due to the latent heat of fusion, which is the energy required to change a substance from liquid to solid at its melting point without a change in temperature.
Why does the temperature not change during a phase change?
During the change of state, the molecules of a substance absorb energy to overcome the strong intermolecular force of attraction between them. Hence the heat energy which we supply is absorbed by them for this purpose. So change in temperature is not observed.
What is the formula for calculating the change in pressure when the volume and temperature of a gas are held constant?
The formula for calculating the change in pressure when the volume and temperature of a gas are held constant is: P (nRT/V)T, where P is the change in pressure, n is the number of moles of gas, R is the gas constant, T is the temperature, V is the volume, and T is the change in temperature.
Can an object that move at a constant speed be accelerating?
No, an object moving at a constant speed cannot be accelerating. Acceleration is defined as a change in velocity over time, so if the speed is constant, there is no change in velocity and therefore no acceleration.
Does the cooling constant in newton's law of cooling change depending on the temperature of the vessel?
No. By definition, the constant does not change with temperature for a given cooling system. The constant "represents" all the particular characteristics of the cooling system, except for the time and temperature variables. If temperature influences the system characteristics, the vessel's dimensions, heat capacity, or heat transfer properties, for example, all of these effects will be completely accounted for by the single constant.
Definition of cooling constant?
newton's cooling constant is defined as the ratio b/w change in temperature and difference in temperature of hot body and temperature of surrounding
The amount of heat necessary to change a liquid to a solid at constant temperature?
None - heat is evolved, not required.
Why does the temperature of any substance remain constant during the change of a state?
because energy is required to break the intermolecular forces in the molecule
A change of phase takes place at a constant what?
A change of phase takes place at a constant temperature.
A change of phase takes place at a constant?
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
Factor that can change equilibrium constant?
Temperature
Why does temperature remain constant when wax solidifies?
Temperature remains constant during the solidification of wax because the heat energy released by the wax as it solidifies is absorbed by its surroundings. This is due to the latent heat of fusion, which is the energy required to change a substance from liquid to solid at its melting point without a change in temperature.
How does temperature change during change of physical change?
Temperature remains constant during the change in phase (physical state).
What happen to the temperature during phase change?
The temperature remain constant.
Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
Can an object be accelerating with constant velocity?
No, since acceleration is defined as a change in velocity. If there is no change, there is no acceleration.
Why does the temperature not change during a phase change?
During the change of state, the molecules of a substance absorb energy to overcome the strong intermolecular force of attraction between them. Hence the heat energy which we supply is absorbed by them for this purpose. So change in temperature is not observed.
