Does it take more heat to heat water or to boil water?
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
What cause a substance to melt?
When a substance is heated, its internal energy increases and causes the particles to move more rapidly, breaking the bonds holding them in a solid state. This results in the substance transitioning from a solid to a liquid state, known as melting. The melting point is the specific temperature at which this transition occurs for a particular substance.
What will happen when atom and molecules of substance melt freeze boil or condense?
When a substance melts, the molecules move more freely and when it freezes, they move more slowly. When a substance boils and becomes a vapor (gas), the molecules again move faster than when in the liquid state, and when the vapor condenses, the molecules move slower.
How can a substance boil to a higher temperature with the same rate of heat provided?
A substance can boil at a higher temperature when the external pressure is increased. This phenomenon is seen in pressure cookers, where the higher pressure raises the boiling point of water. The substance requires more energy to overcome this increased pressure and reach the higher boiling temperature.
When a substance melts or boil it absorbs what?
When a substance melts or boils, it absorbs heat energy from the surroundings in order to overcome the intermolecular forces holding its particles together. This energy is used to break these forces and allow the particles to move more freely, transitioning from a solid to a liquid (melting) or from a liquid to a gas (boiling).
What will happen if you heat a solid substance?
Heating a solid substance usually increases the kinetic energy of its particles, causing them to vibrate and move more rapidly. As a result, the substance may change state, melt into a liquid, or undergo a chemical reaction if it reaches its melting or reaction temperature.
Why does the amount of water affect time it takes to boil?
The basic formula which describes the energy required to raise the temperature of a substance is ΔE=mcΔθ. where: ΔE = Difference in energy m = mass of the substance c = specific heat capacity of the substance Δθ = change in thermodynamic temperature without any calculation, it is clear that if the change in temperature is the same (i.e. from room temperature to boiling point); and the specific heat capacity is the same; the more of the substance that is being boiled; the more energy is required. If the device which is boiling the substance is at a constant power, whether it be a burner or a kettle, the more energy required to boil the substance, the more time it will take to boil so long as the power is held constant.
Does it take more heat to heat water or to boil water?

How causes steel to melt ice?
There is no inherent property of steel that causes it to melt ice. Ice will melt if it comes in contact with something that is warm enough to melt it, regardless of what it is made of. One possible advantage that steel has is that, like any metal, it is a good conductor of heat. This would allow it to transfer heat more quickly than a nonmetallic substance.
How would a microwave oven heat ice versus liquid water?
The actual process of heating would be exactly the same. Microwave energy would begin to excite molecules of water, making them move more quickly and heating them up. Eventually the ice would melt, then boil. The water would heat up then boil.
What does it mean to have a higher specific heat?
Having a higher specific heat means that a substance requires more energy to change its temperature compared to a substance with a lower specific heat. This property can help regulate temperature changes, making substances with higher specific heat more resistant to rapid temperature fluctuations.
What is the relationship between specific heat and the change in temperature of a substance?
Specific heat is the amount of energy it takes to raise a unit mass of the substance by one degree Celsius. For each unit of specific heat applied to a substance its temperature will increase by a set amount.
Why does having more surface melt ice the fastest?
It is because when surface is more, more does the ice get exposed to heat and thus quickly attains heat and energy. This makes it melt faster.
When a substance melts or boil it absorbs what?

This energy is used to break these forces and allow the particles to move more freely, transitioning from a solid to a liquid (melting) or from a liquid to a gas (boiling).
