The energy required to heat a product can be calculated asĭt = temperature difference (K, oC) Example - Required Heat to increase the Temperature in a Piece of Oak See also tabulated values of specific heat of gases, food and foodstuff, metals and semimetals, common liquids and fluids and other common substances as well as values of molar heat capacity of common organic substances and inorganic substances. 1 Btu/lb m oF = 4.187 kJ/kg K = 1 kcal/kg oCįor conversion of units, use the Specific heat online unit converter.If you'd like to learn more about the specific heat of water at the molecular level, check out this video on the specific heat of water from Khan Academy. For comparison sake, it only takes 385 Joules of heat to raise 1 kilogram of copper 1☌. Precisely, water has to absorb 4,184 Joules of heat (1 calorie) for the temperature of one kilogram of water to increase 1☌. One of water's most significant properties is that it takes a lot of energy to heat it. Lucky for me, you, and the fish in the pond to the right, water has a higher specific heat than many other substances. They don't have to worry about either turning on the air conditioner or putting on their woolen flipper gloves. (Also, for happy fish, check out our page on Dissolved Oxygen.) For instance, the fish in this pond are happy because the specific heat of the water in the pond means the temperature of the water will stay relatively the same from day to night. The high specific heat of water has a great deal to do with regulating extremes in the environment. If you've ever held onto a needle and put the other end in a flame you know how fast the needle gets hot, and how fast the heat is moved through the length of the needle to your finger. Metals have a much lower specific heat than water. Dropping an egg on the metal of my car hood on an August day will produce a fried egg. But, if you walk barefoot on the black asphalt of a street in the southern portion of the United States in August, you'll burn your feet. If you leave a bucket of water outside in the sun in summer it will certainly get warm, but not hot enough to boil an egg. A Midwest state, such as Nebraska, will have colder winters and hotter summers than Oregon, which has a higher latitude but has the Pacific Ocean nearby. This property of water is one reason why states on the coast and in the center of the United States can differ so much in temperature patterns. Water surrounding or near cities take longer to heat up and longer to cool down than do land masses, so cities near the oceans will tend to have less change and less extreme temperatures than inland cities. The oceans and lakes help regulate the temperature ranges that billions of people experience in their towns and cities. This same concept can be expanded to a world-wide scale. The high specific heat of water also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual rather than sudden, especially near the oceans. This is why water is valuable to industries and in your car's radiator as a coolant. Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (☌). Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances. There are beaches, as at Porthcressa Beach in Scilly, where tropical plants grow. The specific heat of water is partially responsible for the mild climate along Englands southwestern shore.
