Does specific heat depend on temperature?
Therefore specific heat does not depend on temperature.
What are the three factors affect the heat transfer that is necessary to change an object’s temperature?
Experiments show that the transferred heat depends on three factors—the change in temperature, the mass of the system, and the substance and phase of the substance.
Can the change in temperature be negative?
This is easy. You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees C. For decreases in temperature, the result is negative.
Is specific heat affected by mass?
Specific heat is defined as amount of heat per unit mass of substance that is needed in order to increase the temperature of the substance by one degree celsius. Mass of the substance has no effect on specific heat, as it is already a quantity expressed per unit mass.
How does heat depend on mass?
Heat is a type of energy, but temperature is not energy. Heat depends on mass of the substance, however; temperature does not depend on the quantity of matter. If you give heat to a matter, you increase its temperature or change its phase.
Does the specific heat capacity of a substance depend upon its mass and rise in temperature only?
1 Answer. No, for the same mass and for the same rise in temperature for different substance, the specific heat capacity is found to be different. Thus, specific heat capacity depends upon the nature of the substance also and so its is different for different substances.
Is it true that the more mass a body has the greater its heat capacity explain?
The greater the mass of a body, the greater is its specific heat capacity. If the filament of a 100 W bulb has an area 0.25cm2 and behaves as a perfect block body. Find the wavelength corresponding to the maximum in its energy distribution. Given that Stefan’s constant is σ=5.67×10-8J/m2sK4.
