How to Find Pressure of a Gas Using Temperature & Density?

Through the ideal gas law, the pressure of a gas can be determined when the density, chemical formula and temperature of the gas are known. The ideal gas law is pressure (P) multiplied by volume (V... Read More »

As a person dives toward the bottom of a swimming pool the pressure increases noticeably Does the buoyant force also increase Justify your answer Neglect any change in water density with depth?

The reason why things float is that gravity addresses only the mass regardless the volume. so when a person dives deep, although he moves away the same volume, the buoyant force increases because t... Read More »

What is the difference between low density&high density heating elements?

The density of a heating element in a water heater refers to the wattage of the element in relation to the amount of its surface area. As the elements density lowers, so does the temperature at whi... Read More »
