m= mass
Hf = heat of fusion, which is 334J/g
Hv= 2260J/g
The fusion process involves the phase change of a substance from liquid to solid, which releases energy. To calculate the volume of liquid frozen that produced 1 kJ of energy, you can use the formula: ( Q = m \cdot L_f ), where ( Q ) is the energy released (1 kJ), ( m ) is the mass of the liquid, and ( L_f ) is the latent heat of fusion for the substance. Rearranging the formula allows you to find the mass of the liquid frozen, and knowing the density of the substance will enable you to convert this mass into volume.
The heat fusion (Hf) of a substance is the amount of energy required to change it from a solid to a liquid at its melting point without changing its temperature. To calculate the volume of liquid frozen that produces 1 kJ of energy, you would use the formula: ( Q = m \cdot H_f ), where ( Q ) is the energy in joules, ( m ) is the mass of the substance, and ( H_f ) is the heat of fusion. By rearranging the formula to find ( m ) and then converting mass to volume using the substance's density, you can determine the volume of liquid frozen that results in 1 kJ of energy release.
Frozen thaws to it's original substance, petrified becomes stone.
Ice is solid H2O so it is a pure substance, at least ideally.
A substance can be frozen at room temperature if its freezing point is below the temperature of the room. This can happen with certain substances like liquid nitrogen or dry ice, which have very low freezing points and can transition from a liquid to a solid state at room temperature.
During freezing, energy is transferred from the substance being frozen to its surroundings. As the substance loses heat energy, its temperature decreases until it reaches the freezing point, at which point it transitions from a liquid to a solid state. This transfer of energy continues until the substance is completely frozen.
Freezing involves releasing thermal energy, which is removed from the substance being frozen. This causes the temperature of the substance to decrease until it reaches its freezing point, at which point it solidifies.

Yes, dry ice is a substance. It is frozen carbon dioxide.
Frozen. Any frozen substance is, by definition, solid.
Yes, you can cook a frozen lasagna by following the instructions on the packaging, typically involving baking it in the oven for a specified amount of time.
No, fire is not a substance that can be frozen. It is a process.
During the process of melting and boiling, the heat energy supplied is being used to break the intermolecular forces holding the substance together. This energy is known as latent heat and does not result in a temperature increase because it is being used to change the state of the substance rather than raise its temperature. Once all the substance has melted or boiled, any additional heat energy supplied will then raise the temperature.
