Molar Heat Capacity:The total amount of heat (in joules) required to increase the temperature of one mole of a substance by one Kelvin. Specific Heat Capacity:The total amount of heat (in calories) needed to raise the temperature of one gram of water by one degree Celsius. What is Heat ...
The heat capacity of a substance is a physical property of the substance that gives the amount of energy required to change the temperature of a unit mass of the substance by 1 Kelvin. The common units for heat capacity are {eq}\rm J/g.^\circ C {/...

heat capacity can depend on both ambient pressure and ambient temperature. Scientists often want to know the heat capacity of a gas at a constant pressure, while other variables such as temperature are allowed to change; this is known as the Cp. Similarly, it may be useful to determine a g...
Find the amount of heat energy needed to raise the temperature of 1000 grams (1 liter) of water 1 degree Celsius. The density of mercury, the only metal to exist as a liquid at room temperature, is 13.6 g/cm^3. What is this density in pounds per cubic inch?
Water and the bad smelling molecule hydrogen sulphide do not seem to have a lot in common at first sight. However, when investing a little energy, some differences disappear. At first glance, the ice cube in your soft drink and the smell of grandma’s famous egg salad don’...
energy. This store of gravitational potential energy, originally provided by solar energy that uplifted it, can now create hydro power when converted to the kinetic energy of water flow, in a flux of water in this case, the kinetic energy is usually harvested from the water in a turbine loc...
Thermal conductivity is quantified using the International Systems of Unit (SI unit) of W/m•K (Watts per meter per degree Kelvin) and is the reciprocal of thermal resistivity, which measures the ability of an object to resist heat transfer. It can be calculated using the following equation...
The key thing to look for, therefore, is a jacket (down or synthetic) that has an outer fabric that has a high water-resistant capacity. Pertex Shield fabric is the best for down jackets and nylon is great on synthetic jackets. Versatility: Unless you plan to use your jacket for a part...
The specific heat capacity of materials is called such because it indicates the amount of heat that a gram of that material can store before increasing the temperature by one Kelvin. Specific heat capacities usually vary across...
