Heat It Up

The high specific heat (hsh) is the amount of energy that is absorbed. As a result, water molecules form many hydrogen bonds. A great amount of heat is needed to increase the temperature of liquid water as the heat is also needed to break hydrogen bonds between molecules. The (hshc) is defined as the amount of heat needed to increase the temperature of one gram of a substance to one degree Celsius, this is called a

alcohols in a series were burned to find the amount of heat absorbed per second. The alcohols burnt were Ethanol (CH4O), Propanol(C3H8O), Butanol (C4H10O) and Pentanol (C5H12O). Their flames heated up a calorimeter filled with water. This was incomplete combustion due to the lab conditions. Incomplete combustion “occurs when the supply of air or oxygen is poor.”("BBC - GCSE Bitesize: Combustion", 2017). Complete combustion gives off more energy as heat and is ideal but was unlikely under the test conditions

closes the tap and opens the jar lid easily. Explain why it open easily when placed under hot water for a few mins. Answer: When particles are cold there is barely any movement, and the pickle jar just came out of the cold fridge. I know that when heat is added to a substance, the particles move faster. So when my little sister puts the lid under hot water the particles move faster and the spaces between the particles increase which allows them to bounce off of each other making them more separated

Sautéing have a very high heat and very fewer oils are used. The ingredients are added when the oil heat and have some smoke. Fewer oils are needed because the high heat prevents moisture from being escape and been safer from oil spill and potential cause from the fire. Sautéing can be troublesome due to intense of heat and sound of a food been cooked. Sauté foods had cooked in a thin layer of fat to over medium-high heat, it usually are cooked in a frying pan that on the stovetop. The foods were

Supplemental Zone Heating As temperatures go down, energy costs start to go up and supplementing the heat in your home is the absolute easiest way to lower your energy bills without sacrificing your family's comfort. Supplemental or zone heating is a strategy more and more homeowners are turning to as energy prices continue to rise. The logic behind this is simple. Instead of raising the temperature throughout your entire house, only heat specific areas you use while the rest of the house remains cool.

illustrates the heat pipe as a closed tube where the inner surface is lined with a wick or a porous material that is filled with liquid near its saturation temperature. The liquid in the wick and the open vapour corridor is separated by a vapour-liquid interface, which is found in the inner surface of the wick. Heat pipe characteristics are dependent upon size, shape, material construction, working fluid and heat transfer rate. The operational characteristic of a heat pipe is defined by heat boundaries

is used in every piece of literature to give the writing a since of tone. Rain typically represents a drowsy, sad and mellow atmosphere, while heat brings out the frustration between characters. In The Great Gatsby weather is used in these general terms, but has two very important details that the average reader often overlooks. The two types of weather, heat and rain, are brought to life and acts as a mask to hide the true feeling of the characters. In The Great Gatsby Fitzgerald uses weather as a

aluminum pans and might alter the taste as well. 2. What cookware material is described as low cost and having high (unparalleled) heat capacity? How does this affect the time needed to heat up a pan made of this material? Cast iron is described as having a low cost and having high heat capacity. High heat capacity means that the pan will take longer to heat up compared to other types of pans. 3. Which type of cookware material can be pitted over time when salt is used to cook foods (unless salt

mass of water from calculation #9, the specific heat of water is 4.184 J/g(oC), and the temperature change of water from calculation #7. (10 points) Mass of water: 74.8g Specific heat of water is 4.184 J/g(oC) Change in temp. of water: 1°C Q = 74.8 * 1 * 4.184 = 312.96 J/g(oC) 11. Use the equation: q = m(SH)ΔT to solve for the specific heat of the metal. For q, you found how much heat was gained by the water so you know that same amount of heat was lost by the metal. Therefore, qmetal = -qwater

Q. A young hiker has been on a long walk. He is now sitting in front of a small campfire, drinking a hot cup of soup. It is dark and a frost is beginning to form on his tent. Explain the hiker’s heat gains and losses, and what mechanisms would come into effect to keep his temperature at the desired 37ºC. Humans are subject to vast changes in environmental temperatures, but our complex biochemical systems have a major limitation in that enzymes only operate within a relatively narrow temperature
