Almost nothing is ever infinite in physics.
The specific heat value for water is 4.18 J/goC.
No, it is not possible for the specific heat of a substance to have a negative value.
The keyword "infinite" does not have a specific numerical value on the infinite number line of CodeSignal. It represents a concept of endlessness and is not a specific point on the number line.
Experimental errors would cause the experimental value of specific heat capacity to be higher than the standard value.
Specific heat of water is 1 calory per gram .
The literature value for the specific heat of chromium is approximately 0.449 J/g°C.
No. The first law of thermodynamics implies that the energy of the universe is finite. As a consequence the specific heat of a substance - defined as H/m where H is enthalpy and m is mass. Either H would have to be infinite or m would have to be zero. If m is zero, then the ratio is meaningless because you don't have anything to assign the enthalpy to. H = U+PV. For H to be infinite either U (internal energy) has to be infinite - but we've already established that the 1st law says total energy of the universe is finite, so that's not the case - or PV is infinite. You aren't going to get P (pressure) to be infinite so V would have to be infinite, i.e. zero density - again, if density is zero, there is effectively nothing there. Since we've eliminated all possibilities for any of the necessary terms to be infinite, specific heat cannot be infinite.
Yes.
WATER
Specific heat can be determined without using the heat transfer value by conducting an experiment where the initial and final temperatures of a substance are measured, along with the mass of the substance and the amount of heat added or removed. By using the formula Q mcT, where Q is the heat energy, m is the mass, c is the specific heat, and T is the change in temperature, the specific heat can be calculated.
If boiling water were carried over with the sample, it would increase the measured value of the specific heat. The excess heat energy from the boiling water would contribute to raising the overall temperature of the sample, leading to a higher specific heat value being calculated.
The value of the specific heat ratio (gamma) in air is approximately 1.4 at room temperature. It represents the ratio of specific heats, which is the ratio of the heat capacity at constant pressure to the heat capacity at constant volume.
