Can the specific heat be infinite?

Yes, the specific heat capacity can be zero or infinite. Specific heat capacity is defined as the amount of heat energy required to raise the temperature of unit mass of the substance through 1°C or 1 K.

Does specific heat change with temperature?

In general, the specific heat also depends on the temperature. Table 1 lists representative values of specific heat for various substances. Except for gases, the temperature and volume dependence of the specific heat of most substances is weak.

What is the relationship between specific heat and temperature change of a substance?

The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC. The specific heat c is a property of the substance; its SI unit is J/(kg⋅K) or J/(kg⋅C). Recall that the temperature change (ΔT) is the same in units of kelvin and degrees Celsius.

Which of the substances a B or C has the highest specific heat the temperature vs time graph is shown?

Body B undergoes heating for a greater period of time than that of substance A, but lesser than C. Thus, body C is said to be having greater specific heat than the other substances. Thus, Option (c) is the right answer.

How much heat is gained when water is 5kg?

Heat is a form of energy that is transferred from systems having high temperature to low temperature. Hence, we require 1680 kJ of energy to heat 5 kg of water from $ 20^\circ C\; $ to $ 100^\circ C\; $ .

Can specific heat of a gas be zero or infinity can specific heat of a gas be negative?

Yes, negative specific heat will imply that with rise in temperature ( ΔT is +ve) heat will be released (Q is –ve). This actually happens in case of saturated vapour i.e., specific heat of saturated vapour is negative.

Can specific heat of a gas be zero infinity can specific heat be negative?

Yes, the specific heat of gas will be infinity. Increase in the temperature of gas is zero, for an isothermal process.

What does the specific heat tell you about how easy it is to change the temperature of a material?

A high specific heat means the substance will not change temperature easily. A low specific heat means the substance will change temperature easily.

Is specific heat inversely proportional to temperature change?

Specific heat of a substance is directly proportional to change of heat and inversely proportional to change in temperature.

What is the relationship between specific heat capacity and heat capacity?

Molar heat capacity is a measure of the amount of heat necessary to raise the temperature of one mole of a pure substance by one degree K. Specific heat capacity is a measure of the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree K.

What does it mean if specific heat of a substance is infinite?

Learn the fundamentals of business and how to apply them in your healthcare practice. If specific heat of a substance is infinite it means it is a thermal energy reservoir. It means that substance has infinite capacity to store thermal energy.

What is the difference between specific heat and specific heat?

Specific heat is J g −o K. So, a high value means that it takes MORE energy to raise (or lower) its temperature. A low value means that it does not take very much energy to heat or cool it. Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound.

What does a low specific heat of a compound mean?

A low value means that it does not take very much energy to heat or cool it. Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound.

What is the specific heat of a substance at constant pressure?

Values in parentheses are specific heats at a constant pressure of 1.00 atm. In general, specific heat also depends on temperature. Thus, a precise definition of c for a substance must be given in terms of an infinitesimal change in temperature.
