The figure shows the variation of specific heat capacity (C) of
the rate at which heat is absorbed in the range 0 − 100 K varies linearly with temperature T. heat absorbed in increasing the temperature from 0 − 100 K is less than the heat required for increasing the temperature from 400 − 500 K. there is no change in the rate of heat absorption in range 400 − 500 K.
A sphere of ice 0^{circ}C having initial radius R is placed in an ...
A space object has the shape of a sphere of radius R. Heat sources ensuring the heat evolution at a constant rate are distributed uniformly over its volume. The amount of heat liberated by a unit surface the area is proportional to the fourth power of thermodynamic temperature.

STATEMENT-1: There is a natural asymmetry between converting …
STATEMENT-1: There is a natural asymmetry between converting work to heat and converting heat to work. STATEMENT-2: No process is possible in which the sole result is the absorption of heat from a reservoir and its complete conversion into work. STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is NOT a correct explanation for STATEMENT-1
Which color absorbs the heat?WhiteOrangePinkBlack - Toppr
The correct option is B Black. The more light the object absorbs, the more heat absorbed since light is energy. If you consider it a color, black absorbs the most heat. A black object absorbs all wavelengths of light and reflects none. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.
Give an example of a reaction where the following are involved:
N H 4 C l ( s) + H 2 O ( l) → N H 4 C l ( a q) – H e a t is an example of a reaction where the following are involved in an Absorption of heat. Was this answer helpful?
Heat energy is incident on the surface at the rate of
The coefficient of absorption of a surface is 0.6. When radius heat is incident in the surface at 1500 J / m i n, the energy reflected in 5 minutes is 450 J. The coefficient of transmission of the surface is:
A carnot refrigeration cycle absorbs heat at - Toppr
A carnot refrigeration cycle absorbs heat at 270 K and rejects heat at 300 K. If the cycle is absorbing 1260 K J / m i n at 270 K, then work required per second is : 2.33 K J / s e c. 4.66 K J / s e c. 1 K J / s e c. 4 K J / s e c.
The chemical reaction in which heat is absorbed is known as ...
Chemical reaction which proceeds via absorption of heat energy is called endothermic reaction. These reactions are non-spontaneous reactions in which energy is required to initiate the reaction. These reactions are characterized by the positive heat flow (heat energy flows into the reaction) and increase in enthalpy (greater than zero).
