The amount of heat of a material required to raise the temperature of either one kilogram or one gram of that material by one degree Celsius. Different units may be used depending on whether specific heat is measured in s of grams or kilograms, and joules or calories.
Cp is the specific heat capacity at constant pressure. It specifies the amount of heat required to raise the temperature of 1 kg of material by 1Â°C (K). It is measured by the standard technique of calorimetry.
(Thermal Capacity) - This defines how much heat is needed to raise the temperature of one pound of material one degree Fahrenheit. Units - BTUs per pound per degree Fahrenheit (BTA/lb/°F) - Joules/Kilogram Kelvin (J/KgK). Higher numbers means that it takes more input heat energy to raise the temperature of a material.
The ability to absorb and communicate large quantities of heat. It is much harder to raise the temperature of water than air. A layer of water around the body does not insulate, but instead conducts heat. The temperature of pool water (approximately 83 degrees) decreases the load on the heart by assisting in cooling the body. Evaporation of sweat is one of the most important ways the body loses heat after immersion in a pool. Heat is lost much faster in water than air, allowing far greater training intensities and durations. The water's ability to cool the body is also a benefit far people who tend to overheat while exercising, and in conditions such as pregnancy or multiple sclerosis, where maintaining a lower core body temperature is very important.
The amount of heat energy that can be contained in a given weight of a substance compared to the amount of heat energy that can be contained in the same weight of water; expressed as a ratio with water equaling a specific heat of one (1)
The heat required to raise a unit mass of a substance one degreee kelvin. It is the heat capacity of a system per unit mass; i.e., the ratio of the heat absorbed (or released) to the corresponding temperature rise (or fall).
(Heat Capacity) is the rate of change in enthalpy with temperature. It is commonly measured at constant pressure or at constant volume. The values are different and are known as cp and cv respectively.
Compare with heat capacity. The heat required to raise the temperature of 1 g of a substance by 1°C is called the specific heat of the substance. Specific heat is an intensive property with units of J g-1 K-1.
Temperature is measure of heat energy level whereas heat is a measure of total internal energy contained in a body. When the same quantity of heat is given to equal masses of different substances, they do not result in the same rise in temperature. The specific heat is defined as the quantity of heat energy which will rise the temperature of unit mass (1kg) of a substance by 10C. Heat = mass x specific heat x Temperature rise.
1. The quantity of heat, expressed in Btu, required to raise the temperature of 1 lb of a substance 1°F. 2. The ratio of the thermal capacity of a substance to that of water. The specific heat at constant pressure of a gas is designated cp. The specific heat at constant volume of a gas is designated cv. The ratio of the two (cp/cv), is called the ratio of specific heats, k.
Ratio of the heat capacity of a substance to the heat capacity of water. The quantity of heat required for a 1°F temperature change per unit weight of material. Water = 1.0 Btu's/lb/°F. Most organic substances are less than 0.5, most organic solvents are between 0.4 and 0.7 and steel is 0.12.
A property of materials. The specific heat of a material indicates how much thermal energy (in joules) is required to increase a mass (in grams) of material a small temperature difference (degree C). Specific heat is one of the principal factors in determining heat capacity, conduction rates in a material ' and the thermal time constant of an object subject to heating.
