Specific heat capacity is by definition a per-unit-mass property. Therefore it does not depend on the mass of the substance.

What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
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.
Will concrete brick aluminum or copper take most energy to increase its temperature?
Whichever of them has the lowest specific heat capacity will take the least energy to raise its temperature, and whichever has the highest specific heat capacity will take the most energy.
If the heat capacity of an object is known what other information will need to be known to calculate its specific heat capacity?
By using the definition of "specific heat". You add a certain amount of heat, and see how much the temperature increases. You also need to measure the sample's mass. Then divide the amount of heat by (mass x temperature increase).
Will the same mass of iron and water require the same amount of heat to increase their temperature the same number of degrees?
No, no. Of course not. The amount of heat Q required to increase the temperature of a body of mass m having specific heat capacity c through DO degrees celsius is given by: Q = mcDO Thus, the one with the higher specific heat capacity will require more heat energy.
Would substances with high specific heat capacity also have high temperatures?
Specific heat capacity is the amount of energy or heat required to raise the temperature of a unit mass of a substance by one kelvin. So if the specific heat capacity is high then you would require more energy or heat to raise its temperature. The specific heat capacity does not really have anything to do with how much you can increase an objects temperature. IT HAS TO DO WITH THE ENERGY NEEDED TO INCREASE THE TEMPERATURE.
What is the relationship between the density and the specific heat capacity of a pure substance?
Density is directly proportional to the specific heat.
What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
What is the definition of specific heat (apex)?
the amount of heat need to increase the temperature of 1 g of a substnace 1 C; also called specific heat capacity
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.

Effect of temperature on specific heat of material?
The effect of temperature on specific heat of material is referred to as specific heat capacity.

50g of a substance's temperature increase from 20C to 40C when it absorbs 250 calories of heat What are its heat capacity and its specific heat in joules?
345 J ok good
Will the same mass of iron and water require the same amount of heat to increase their temperature the same number of degrees?
No, no. Of course not. The amount of heat Q required to increase the temperature of a body of mass m having specific heat capacity c through DO degrees celsius is given by: Q = mcDO Thus, the one with the higher specific heat capacity will require more heat energy.
