Specific heat is how much heat energy is needed raise the temperature of a substance. Water has a very high specific heat. That means it needs to absorb a lot of energy before its temperature changes. Sand and asphalt, on the other hand, have lower specific heats. This means that their ...
Chemists call them degrees of freedom. Every mechanical movement that an atom or molecule displays supplements the total thermal energy of the system. Polyatomic molecules have higher degrees of freedom because of the bonds present in them and, thus, have greater specific heats than their mono...
Water’s specific heat is one of its most interesting characteristics.In this article, we’ll be covering what specific heat is, what equation you use to find specific heat, and why water’s specific heat is so high. The stove, pot, water, and steam all have different specific heats. Wh...
' " The Variable and Absolute Specific Heats of Water." By JOHN MACFARLANE GRAY. IN Rankine's " Nanual of the Steam Engine," Article 212, occurs the following sentence : "The fact the that increase of the specific heat of solids andliquidsasthetemperature rises is greatest for those ...
from this observation, he founded the concept of specific heat. In the early 19th century the French physicistsPierre-Louis Dulong andAlexis-Thérèse Petit demonstrated that measurements of specific heats of substances allow calculation of theiratomic weights(seeDulong-Petit law).See alsoheat capacity...
The heat capacity and temperature are proportional to each other. On increasing the heat capacity of water, its temperature also increases. The...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer y...
However, in the case of liquids and solids, the difference between ‘constant pressure’ and ‘constant volume’ specific heats becomes less significant as the volume of liquid and solid substances vary insignificantly. Sign in to download full-size image 4.2. The specific heat of water varying ...

specific heat, ratio of the heat capacity of a substance to the heat capacity of a reference substance, usually water. Heat capacity is the amount of heat needed to change the temperature of a unit mass 1°. The heat capacity of water is 1 calorie per gram per degree Celsius (1 cal/g...
