The specific heat capacity of water does not change much within-phase (ie, as a solid it has one specific heat capacity, as a liquid/gas it has another)

What does water help to regulate?
Water's high specific heat capacity helps to maintain body temperature. High specific heat capacity indicates a need for more energy to raise or lower the temperature of water. Sweat is another way that water helps maintain temperature. When sweat evaporates it draws in energy from the surroundings (the air and the body surfaces it is in contact with), effectively lowering the temperature.
Does it take more energy as heat to raise the temperature of water by one degree than to raise the temperature of steam by the same amount?
Yes. The specific heat capacity of liquid water is 4.184 J/g•oC, and the specific heat capacity of steam is 2.010 J/g•oC.
What does it mean to say that a material has a high or low specific heat capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.
Why specific heat capacity increase with temperature?
Specific heat capacity is by definition a per-unit-mass property. Therefore it does not depend on the mass of the substance.
Water changes temperature less readily than other liquids because it has High?
It's called specific heat capacity.

What property of water makes it so your high temperature will go down?
Water has a high heat capacity and a high specific heat capacity 4.184 kJ/kg/K
What does the amount of energy needed to heat water depend on?
The equation Q=mcΔ t calculates the amount of energy for a body of mass to raise a unit temperature per unit mass. The specific heat capacity of water is 4.19 J/g°C which means that it takes 4.19 J to raise 1 g of water to 1°. The specific heat capacity also depends on what the surrounding temperature is. 4.19 J/g°C is the specific heat capacity at room temperature. Since temperature is the measurement of the average kinetic energy of the particles, the motion of particles in water affects the specific heat capacity which ultimately affects how much energy is needed to heat up water.

Does the mass of water affect temperature rise?
Yes due to something called 'specific heat capacity', this is basically that the more water there is, the hotter it can get.
Which item requires the least energy to increase its temperature lounge chair sand or water Explain your answer in terms of this item's specific heat?
Sand needs least energy to increase the temperature as its specific heat is very low compared to that of water. Water needs more energy to increase its temperature as its specific heat capacity is higher.
Why specific heat capacity increase with temperature?
Specific heat capacity is by definition a per-unit-mass property. Therefore it does not depend on the mass of the substance.
Why should you stir the water at the end of the experiment specific heat capacity?
To make sure that there are no temperature gradients and that is the heat is distributed uniformly.
Water changes temperature less readily than other liquids because it has High?
It's called specific heat capacity.
Relative humdity is a ratio of what?
The mass of water vapour in a given quantity of air to the maximum mass of water vapour that it could hold - at the specific temperature and pressure.
What is the quantity of heat energy required to raise the temperature of a unit mass of a substance?
If the substance is water, this is the kilocalorie (1000 calories). One calorie is the heat to raise one gram of water by 1 deg C. Other substances don't have the same specific heat capacity as water, so you have to correct for that, first find out the heat capacity (specific heat) for the substance you are dealing with.
