At normal temperature, fuels are stable even in the presence of air. This is because, the activation energy of combustion reaction is high. When a mixture of fuel and air is burned, a flame has to be applied, that is the mixture has to be ignited. Near the flame, the contents are raised to high tem..

This theory explains the physical properties of matter in terms of motion of its molecules. According to this theory, every substance (solid, liquid or gas) consists of a large number of minute particles called molecules. A molecule may be defined as the smallest particle of a substance that ..

Let us consider one-gram molecule (mole) of the gas. Let M and V be its mass and volume respectivel..

We know that a hotter body has greater internal energy than a similar colder body. Thus, higher temperature means higher internal energy and lower temperature means lower internal energ..

Boyle's law - At a given temperature, the pressure of a given mass of a gas is inversely proportional to its volume. This is Boyle's law. From equation (vi), we have -----(a) As for a given gas, T , the value of is constant at a given temperature. In addition, for a given mass of the gas, m and N a..

Under normal conditions matter exists in three forms: solid liquid gas Matter is made up of atoms and molecules. These atoms in molecules are in a state of continuous motion. For example, molecules and atoms of a solid can have only vibrational motion, because they are held in their positions by st..

Consider a body of mass 'm' which is initially at rest. When a force 'F' is applied on the body, let it start moving with a velocity 'V' and cover a distance 's'. The force produces acceleration 'a' in the body. The force 'F' does work when it moves the body through a distance 's' and this work don..

It is clear from equation (2) that the mean kinetic energy of a molecule is directly proportional to the Kelvin (or absolute) temperature of a gas. When the temperature of the gas is increased, the mean kinetic energy of the molecules increases. On the other hand, when heat ..

Tony, who weighs 36 kgs, is running in a football field. If he has acquired 72 joules of kinetic energy, then what is the velocity with which he is running? Kinetic energy is modeled by the equation E = 1 2 × m × v 2 , where E is the kinetic energy, m is th..

The kinetic energy E, of a body moving with a velocity v is given by the equation E = 1 2 m v 2 , where m is the mass of the body. Find the mass of a body moving with a velocity 67 m/s and having an energy of 1541 N. (Round the answer to two decimal places.) => 1.19 kg or 23 kg or 0.69 kg..
