We know that
Q=m.s.t, where Q= Heat, s= Specific heat of the substance, t=temperature(Difference in temperatures)
=>s= Q/m.t
=>s=525/(25X15)
=>s=525/375
=>s=1.4 cal/g/0c
Specific heat of the substance is 1.4 cal/g/0c.

What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What is the specific heat of a substance?
The amount of heat a substance can hold.
The specific heat of substance A is greater than that for substance B If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these s?
The specific heat of substance A is greater than that for substance B. If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these samples, substance A will have a lower temperature than substance B.
What is used to find the specific heat capacity of a substance?
The equation for specific heat is: C = q/temp. change x mass. C is a substance's specific heat, which is a constant for every substance. q is its heat capacity in joules, temp. change is the change in temperature in degrees Celsius, and mass is in grams.
The fundamental density is the ratio of the mass of a substance to its volume this is known as what?
its density. note. density is often expressed as the ratio of the density of the substance to the density of water at standard temperature and pressure. This is known as the specific gravity of the substance. It is a dimensionless number so it has no units.
What is the specific heat of 40g of a substance if it requires 195.3 calories of energy to raise its temperature from 5 to 15 degrees Celsius?
488.25 J/kg/*C
Give an example where one substance has a lower specific heat therefore requires less energy to increase in temperature?
An example of one substance has a lower specific heat and requires less energy to increase in temperature is tomato sauce.
What is a substance that has a specific heat?
Every substance has a specific heat. The definition of specific heat is: The amount of energy, usually measured in calories, needed to raise the temperature of one gram of a certain substance by one degree Celsius.
What is the quantity of heat in joules or calories required to raise the temperature of 1 gram of a substance 1C?

What substance is used as the standard against which you measure specific heats?
If you can measure 3 of these 4 things then you can use this formula q( energy in Joules ) = Mass * specific heat * temperature final - temperature initial
What requires to rise 1 g of a substance 1°?
The specific heat is the amount of heat required to raise the temperature of 1 g of substance by one degree Celsius or one Kelvin.
If 1 gram of iron requires 0.11 calories to raise the temperature 1 degree Celsius what is iron's specific heat?
0.11cal/g degrees C
What is the importance of congealing temperature?
congealing temperature is a temperature at which a substance congeals (turns from liquid into solid fase). This temperature is specific for a substance and can therefore help to identify the substance.
