Specific heat capacity questions and equation - alanpedia

Experiments have shown that the heat transfer Q = mcΔT, where ΔT = Tfinal-Tinitial of the object you’re considering, m is its mass, and c is referred to as the “specific heat” of the material it’s made up of. For most materials over a wide range of temperatures, c is close enough to a constant value that we will consider it to be exactly constant.

Aluminium foil - Wikipedia

Aluminium foil, often referred to with the misnomer tin foil, is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm; thinner gauges down to 6 micrometres are also commonly used. In the United States, foils are commonly gauged in thousandths of an inch or mils. Standard household foil is typically 0.016 mm thick, and heavy duty household foil is typically 0.024 mm. The foil is pliable, and

Stress Strain Curve: What Exactly Is The Stress-Strain Curve?

The stress-strain graph provides engineers and designers a graphical measure of the strength and elasticity of a material. It allows them to predict the behavior of materials used in a given application. To draw the graph, the material must first undergo a tensile test. A tensile test is the simplest and most widely implemented mechanical test.

To test the effect of surface color, I baked three 12 oz Idaho potatoes in a 250F oven. One bare, one wrapped in shiny aluminum foil, and one in black foil. 250F is a slow oven, and more likely to dessicate than bake, but the results were telling: The black potato cooked first, the aluminum-foiled second, and the bare potato in a close third.

Temperature Difference. In the graphs above, the slope of the line represents the rate at which the temperature of each individual sample of water is changing. The temperature is changing because of the heat transfer from the hot to the cold water. The hot water is losing energy, so its slope is negative.
