(General Physics) the heat required to raise unit mass of a substance by unit temperature interval under specified conditions, such as constant pressure: usually measured in joules per kelvin per kilogram. Symbol:cp(for constant pressure) Also called:specific heat ...
Latent heat of a substance is the amount of energy absorbed or released by the substance during a change in its physical state that occurs without changing
On the other hand, Sekhar and Sharma equation [22] does not fit any of our experimental data. Show abstract Effect of magnetic field on the physical properties of water 2018, Results in Physics Citation Excerpt : The schematic diagram of magnetization is shown in Fig. 2. DSC (Differential ...
The equation says that the sum of all the heat transfers must be zero as the iron loses heat (negative ΔTiron) and the copper and water gain heat (positive ΔTcopper+water). In other words, the changes in temperature are algebraic quantities, that could be positive or negative. So ...
Measurements of the specific heat of thallium at liquid helium temperatures Specific heats of thallium were measured from 1.3 to 4.2° K. The atomic heat of thallium shows a change of 0.00148 cal/°K. mol. at the transition point. This agrees with Rutgers' equation. No latent heat was obser...
Moldoveanu and Minea27, based on their examinations measuring the specific heat capacities of TiO2/W, SiO2/W, and Al2O3/W nanofluids, modified Sekhar and Sharma’s24 equation to propose another correlation. Its validity was limited to a range of room temperatures and volume fractions of less ...
calculated from the specific-heat data and compared with that calculated from (i) measurement of the latent heat at the B → A transition, and (ii) measurement of the suppression of the B transition by magnetic field, B phase susceptibility data, and a magnetic Clausius-Clapeyron equation. Th...

- From the equation, we can express the change in temperature (ΔT) as: ΔT=Qm⋅C - This shows that ΔT is directly proportional to the heat added (Q) and inversely proportional to the specific heat capacity (C). 3. Comparing the Specific Heat Capacities: - Given: - Specific heat...
To find the energy required to raise the temperature of a 2g substance from 0°C to 5°C, we will use the specific heat capacity equation given as:
