The heat depends on the mass of a substance as there are more particles to heat up. When one particle is given energy from the heat, it moves around on it's fixed point (in a solid). When it touches the next particle, the energy is passed along warming the object up right the way through. This is called conduction.

What does heat capacity depend on?
Mass and specific heat.
Does the amount of heat in a substance depend on the motion of the molecules?
yes
What conversion does the value of the conversion factor depend upon the formula of the substance?
mass of any substance to moles
What is the reason for heat transfer from one substance to another difference in mass?
Difference in temperature is the reason heat transfers from one substance to another.
Is specific heat capacity inversly proportional to its mass?
No. Specific heat capacity is 'normalized' with respect to mass, so it's a property of the substance, regardless of the mass of the sample.
How do you work out the quantity of heat?
by dividing the quantity of heat of a substance by the mass of that substance
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.
What does heat capacity depend on?
Mass and specific heat.
Does the amount of heat in a substance depend on the motion of the molecules?
yes
What happens to heat capacity if mass id doubled?
Heat capacity is measured either for one gram or one mole of a substance so the mass of substance does not matter.
Does the density of a substance depend on mass and volume?
yes, to find the density, you do mass divided by volume
Why is density a characteristic of a substance and volume and mass are not?
The volume and mass of a substance are independent of the substance itself, but depend upon how much there is of the substance The density of a substance is the relation between how much volume you have of a substance and how much mass that volume has (and vice-versa). It is independent of how much there is of the substance and is thus a characteristic of the substance.
What conversion does the value of the conversion factor depend upon the formula of the substance?
mass of any substance to moles
What does the amount of movement between particles depend on?
Mass
What is the reason for heat transfer from one substance to another difference in mass?
Difference in temperature is the reason heat transfers from one substance to another.
Is specific heat capacity inversly proportional to its mass?
No. Specific heat capacity is 'normalized' with respect to mass, so it's a property of the substance, regardless of the mass of the sample.
Why cant heat travel from the grill to toast by convention?
Conduction is the process of heat diffusing through a substance that conducts heat. The less conductive the substance is (like glass, air, or an oven glove), the slower the conduction is. Convection is the movement of heat that occurs when a mass of hot substance physically moves to another location. Both of these mechanisms depend on the presence of a material substance to move heat from place to place, and the efficiency of the mechanism depends on the characteristics of the substance. Radiation is the movement of heat in the form of electromagnetic radiation. It doesn't require any substance in the intervening space to transfer the heat; in fact, it is most efficient when there is NOTHING in the way. That's how heat reaches us from the sun.
