The specific heat capacity<\/strong> o specific heat<\/strong> is the amount of heat that must be contributed to a unit mass of a thermodynamic substance or system to raise its temperature by one unit. The specific heat depends on the value of the initial temperature. It is represented by the letter\u00a0 c.<\/strong><\/em><\/p>\n The heat capacity is the amount of heat that must be brought to the entire mass of a material to raise its temperature by one unit. It is represented by the letter C.<\/em><\/strong><\/p>\n The ratio of the specific heat to the specific capacity is therefore the mass of the element. The specific heat is a property that can be defined for an chemical element<\/a>while for the heat capacity it is necessary to know the mass.<\/p>\n Heat capacity is of great importance in many aspects of our daily lives. The first aspect would be the climate, through the water of the oceans, that regulate the planet's climate<\/a>. Due to the high heat capacity of water, a lot of heat is required to raise its temperature.<\/p>\n This means that in areas close to the sea, the temperature throughout the year is more constant than in remote areas. At the beginning of summer the water temperature is low and even if it is very hot on the shore, the water does not heat up immediately, maintaining a not so hot climate. In winter the process is the other way round, the water temperature does not drop so quickly and maintains a mild climate in winter.<\/p>\n In the particular case of water, the specific heat,\u00a0c<\/i>\u00a0is 1 cal\/(g \u00baC) or 4186 J(kg \u00baK). This means that 1 calorie is needed to raise the temperature of the water by 1\u00baC. It is expressed in J\/Kg\u00baK because they are the units of measurement of the International System, being in this case 4186 Joules to raise 1\u00baK 1Kg of water.<\/p>\n To obtain the mass heat capacity, multiply the specific heat (in grams or kg, depending on the units you use) by the mass.<\/p>\n <\/p>","protected":false},"excerpt":{"rendered":" The specific heat capacity or specific heat is the amount of heat that must be brought to a unit mass of a thermodynamic substance or system to raise its temperature by one unit.
