Distilled water can be cooled to an extremely low temperature before it starts to freeze. When ice begins forming, it will warm up to 0 Celsius (32 Fahrenheit) until all the water is frozen. In a microwave it can get as hot as 120 degrees Celsius (240 Fahrenheit) before it starts to boil. Then when it starts to boil, it will cool down to 100 Celsius (220 Fahrenheit) until it has all evaporated. (That is why it can be dangerous to pull a hot coffee cup out of a microwave oven. Water above boiling point can scald your hand.)

Does the temperature of a substance change before the change of state is complete?
No. During a phase change the temperature is constant until the phase change is complete.
Does the temperature of a substance changes before the change of state is completed?
No. During a phase change the temperature is constant until the phase change is complete.
When a substance is undergoing a chance of state the temperature of the substance does not change until the?
change is complete
What is the temperature of a substance does not change before the?
The Phase Change is complete, e.g water melting from ice phase to liquid phase or water evaporating from liquid to gas. Save
When a substance is undergoing change of state the temperature of the substance does not change until the is complete?
During a change of state, such as melting or boiling, the temperature of the substance remains constant because the heat energy is being used to break intermolecular forces rather than increase the kinetic energy of the particles. Once the change of state is complete, the temperature will start to rise again as thermal energy is being used to increase kinetic energy.
How can you add heat to a substance without raising its temperature?
One way to add heat to a substance without raising its temperature is by changing its state of matter. This process, known as phase change, involves adding heat energy to a substance to change it from a solid to a liquid or from a liquid to a gas. During this phase change, the temperature of the substance remains constant until the phase change is complete.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
How does specific heat of a substance relate to temperature change?
A substance with a high specific heat will easily change temperature.
How does the specific heat of a substance relate to temperature change?
A substance with a high specific heat will easily change temperature.
How can the temperature of a substance remain the same even if the substance is absorbing thermal enerrgy?
The temperature of a substance can remain the same during absorbing thermal energy if the substance is undergoing a phase change, such as melting or boiling. During a phase change, the absorbed thermal energy goes into breaking intermolecular bonds rather than increasing the temperature. Once the phase change is complete, the temperature will resume rising as the substance absorbs more thermal energy.
What happens to a substances temperature during a phase change?
stays the same
What causes a substance to change a phase?
change in temperature
