independence from the environment. Regulating body temperature is one instance where homeostasis occurs (Thermoregulation). Some methods are conduction‚ where the body absorbs/removes heat via contact surfaces; convection‚ which is the upward flow of warm air or the downward flow of cold air past the body; radiation‚ where heat is transferred/received via infrared waves on non-contact surfaces; evaporation where water on the body is evaporated giving a cooling effect. To maintain a constant body temperature

energy is like living in darkness. Based on my knowledge‚ CO2 that emits to the air will go up to the atmosphere and damage the O3 layer on the atmosphere. This would cause what we called the glass house effect. The glass house effect occurs when the heat from the earth cannot emits to the outer space again‚ and this will cause the earth’s temperature to raise and cause a global warming. Not only that CO2 can damage the earth‚ but also human’s health since CO2 is not healthy for human’s lung. More sickness

Other than that‚ it’s an obvious uses there are a lot of our everyday products

Take a piece of aluminum foil and place on the table top to catch any spills‚ and it also can be used to reflect heat upward. Set the burner stand over the aluminum foil and place the beaker of water on top of the burner stand. Measure and record the initial temperature of water.

The greenhouse gas effect The greenhouse gas effect is the accumulation of natural and man-made gas in the atmosphere which does not block sunlight but trap heat to keep the temperature on Earth suitable for life. Imagine a greenhouse that is made of glass that supports plants growth. Visible sunlight can go through the glass but the heat in which it contains can’t go back through the glass‚ thus a greenhouse keeps plants warm allowing them to live and grow happily. The same process with gas replacing

Insulating buildings more effectively‚ changing the industry process and driving aerodynamic cars would reduce the demand for energy use. Some household appliances conserve energy. A desktop computer generates less heat and is made of recyclable materials. A dishwasher has a booster heater that raises

plastic cup in this experiment is that the plastic material is too thin which will cause the outside surface of the plastic cup to be hot due to conduction. Furthermore‚ plastic is not a good insulator as compared to polystyrene cup and this will cause heat loss which will affect the reading of the experiment ii)NaOH is a strong alkaline solution that can cause severe chemical burns if it is in contact with skin f)i) Since the paper coffee cup gets so hot‚ many coffee shops provide a thin cardboard

A certain fluid at 10 bar is contained in a cylinder behind a piston‚ the initial volume being 0.05 m3. Calculate the work done by the fluid when it expands reversibly: a. at constant pressure to a final volume of 0.2 m3; b. according to a linear law to a final volume of 0.2 m3 and a final pressure of 2 bar; c. according to
