How many kj of heat are needed to raise the temperature of 10.00kg of liquid water from 24.6-46.2?
The specific heat capacity of water is about 4.18 J/g°C. First, convert 10.00 kg to grams (10,000 g). Then calculate the change in temperature (46.2 - 24.6 = 21.6°C). Finally, use the formula Q = mcΔT to find the heat required: Q = 10,000g * 4.18 J/g°C * 21.6°C. Convert the result from joules to kilojoules for the final answer.

What is needed for water to change from a solid to a liquid?
A room temperature ubove 0 degrees centigrade.
What is the amount of heat needed to change 1 kg of a specific material from liquid to vapor at a constant temperature?
The amount of heat needed to change 1 kg of a material from liquid to vapor at a constant temperature is called the latent heat of vaporization. This value varies depending on the material and is typically provided in joules/kg.
A substance that has a specific heat that is higher than liquid water and explain what it means?
that means more energy is needed to raise the temperature of 1kg of liquid from 1 Celsius than water.
What is saturated heat?
Saturated heat refers to the amount of heat required to convert a substance from a solid to a liquid or from a liquid to a gas at its boiling or melting point, while keeping the temperature constant. It represents the energy needed for a phase change to occur without changing the temperature of the substance.
What energy is required to create a phase change without changing the temperature?
The energy required to create a phase change without changing the temperature is known as latent heat. This energy is needed to break the intermolecular forces holding the molecules in a particular phase, such as solid to liquid or liquid to gas, without increasing the temperature of the substance.
What temperature change is needed to change a liquid into a solid?
it depends on what type of liquid it is
What is ment by the term flashpoint in relation to fuels?
It is the lowest temperature at which the vapour of a flammable liquid will ignite in air. The flashpoint is generally lower than the temperature needed for the liquid itself to ignite
What conditions are needed for liquid water?
Temperature higher than freezing and lower than boiling.
What is needed for water to change from a solid to a liquid?
A room temperature ubove 0 degrees centigrade.
What conditions are needed for evaporation?
Evaporation occurs when a liquid turns into a gas at a temperature below its boiling point. It requires heat energy to break the intermolecular forces holding the liquid molecules together. Additionally, an open surface area is needed for the liquid to escape as a gas.
What is the engery required to go from liquid to gas called?
The energy required to go from liquid to gas is called heat of vaporization. This is the amount of energy needed to change a substance from a liquid into a gas at constant temperature and pressure.
What is needed to change water from a solid to a liquid?
A room temperature ubove 0 degrees centigrade.
What is the amount of heat needed to change 1 kg of a specific material from liquid to vapor at a constant temperature?
The amount of heat needed to change 1 kg of a material from liquid to vapor at a constant temperature is called the latent heat of vaporization. This value varies depending on the material and is typically provided in joules/kg.
What is water and heat of vaporization?
Heat of Vaporization id the amount of heat needed to transform a liquid into a gas while not raising its temperature.
A substance that has a specific heat that is higher than liquid water and explain what it means?
that means more energy is needed to raise the temperature of 1kg of liquid from 1 Celsius than water.
What is the heat energy needed to change a liquid to gas while the temperature stays the same?
The heat energy needed to change a liquid to gas while the temperature stays the same is called the heat of vaporization. This energy is used to overcome the intermolecular forces holding the liquid molecules together and convert them into a gas. It is a phase change process that occurs at the boiling point of the substance.
Is it possable to add heat but not change the temperature of somthing?
Yes, it is possible to add heat to something without changing its temperature. This can happen during a phase change, such as when melting a solid into a liquid or evaporating a liquid into a gas, where the added heat provides the energy needed for the molecules to change their arrangement without a change in temperature.
