The most obvious difference: A sperm cell is a reproductive cell of males while egg cells are of females. Both egg cells and sperm cells depend on each other for the reproduction of a human life. Both egg cells and sperm cells undergo meiosis.
Explanation:
Answer:
At 100°C, the water is present in two states: Liquid and gases.
At this temperature, the water molecules get converted into vapor state. The energy of the vapor or steam particles is more than the water molecules although they are present at the same temperature because of the presence of Latent heat of vaporization.
Latent heat of vaporization is defined as the amount of energy required to convert a liquid into gas at constant temperature and pressure. This energy is hidden in the physical process.
Because of this heat, the particles of steam have more energy than water at same temperature.
particles in steam at hundred degree Celsius and 373 degree Kelvin will have more energy than the water at same temperature because the steam would have observed the latent heat of vaporization which is equal to 540 calories
