Vedantu academic counsellor will be calling you shortly for your Online Counselling session. Related Questions. Answer Verified. Hint: We have to obtain a relation in Temperature T and time t from the given information. Using this information, we can eliminate option D.

We consider isolated systems, unless otherwise stated, so that no heat is lost to the environment and the principle of conservation of energy can be applied to work out the answer. If the liquids are removed from their recipients and mixed, the final temperature would be around:. Comments: It is important to observe the SI units. The mass is in kg and the heat energy in J. Normally the temperature is converted into K, but because we are taking the difference or the variation , it doesn't matter what units are used if kelvin or celsius. However, if the difference of temperatures can be plugged in the formula in the scales kelvin or celsius no need to convert celsius into kelvin. If the difference is in degrees farenheit a conversion to celsius or kelvin is needed before using the formula.

Specific heat capacity

In thermodynamics , the specific heat capacity symbol c p of a substance is the heat capacity of a sample of the substance divided by the mass of the sample. Informally, it is the amount of energy that must be added, in the form of heat , to one unit of mass of the substance in order to cause an increase of one unit in temperature. The specific heat capacity often varies with temperature, and is different for each state of matter. The specific heat of a substance, especially a gas, may be significantly higher when it is allowed to expand as it is heated specific heat at constant pressure than when is heated in a closed vessel that prevents expansion specific heat at constant volume. Specific heat relates to other intensive measures of heat capacity with other denominators.
