WebThe difference is mostly due to the fact that air is a gas and the water is a liquid, because density depends a lot on the state of matter. In a solid, the particles are tightly packed, so … WebFeb 28, 2024 · For a perfect gas at any particular temperature, a given volume contains a constant number of molecules. (The common formulation is that at standard temperature and pressure, one mole of gas occupies 22.4 litres). The molecular weight of water is around 16, that of air around 30. But you said "box" not "balloon".
WebChemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. For example, chemical … WebJul 20, 2024 · 8.6: Drag Forces in Fluids. When a solid object moves through a fluid it will experience a resistive force, called the drag force, opposing its motion. The fluid may be a liquid or a gas. This force is a very complicated force that depends on both the properties of the object and the properties of the fluid.
Gas is one of the four fundamental states of matter. The others are solid, liquid, and plasma. A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A … See more The only chemical elements that are stable diatomic homonuclear molecular gases at STP are hydrogen (H2), nitrogen (N2), oxygen (O2), and two halogens: fluorine (F2) and chlorine (Cl2). When grouped together with the See more When observing a gas, it is typical to specify a frame of reference or length scale. A larger length scale corresponds to a macroscopic or global point of view of the gas. This region (referred to as a volume) must be sufficient in size to contain a large … See more An equation of state (for gases) is a mathematical model used to roughly describe or predict the state properties of a gas.

In 1662 Robert Boyle performed a series of experiments employing a J-shaped glass tube, which was sealed on one end. Mercury was added … See more The word gas was first used by the early 17th-century Flemish chemist Jan Baptist van Helmont. He identified carbon dioxide, the first known gas other than air. Van Helmont's word … See more Because most gases are difficult to observe directly, they are described through the use of four physical properties or macroscopic characteristics: pressure, volume, number of particles (chemists group them by moles) and temperature. These four … See more If one could observe a gas under a powerful microscope, one would see a collection of particles without any definite shape or volume that are in more or less random motion. These gas particles only change direction when they collide with another particle or … See more WebBut it is quite easy to do a separate experiment to determine the total heat capacity of the calorimeter. You often set up your calculations like this: heat for water + heat for object + heat for calorimeter = 0. q₁ + q₂ + q₃ = 0. q₁ = m₁s₁ΔT₁ for the water. q₂ = m₂s₂ΔT₂ for the object. q₃ = CΔT for the calorimeter.
