water boils at 100°C and turns into steam. Which similarities or differences are there between water at 100°C and steam at 100°C.
1. The particles will have more space between them as a liquid, but they will be moving at the same speed in both states.
2. The particles will have more space between them as steam, but they will be moving at the same speed in both states.
3. the particles will have more space between them as a liquid, but they will be moving faster as steam.
4. Particles will have more space between them and they will be moving at higher speed as steam.
All of the given options are correct.
1. The particles will have more space between them as a liquid, but they will be moving at the same speed in both states. This is because liquid water has a higher density compared to steam, so the particles are closer together. However, the kinetic energy of the particles, which determines their speed, remains the same.
2. The particles will have more space between them as steam, but they will be moving at the same speed in both states. As steam, the water molecules are further apart due to the increased temperature and the change in intermolecular forces, but their speed remains the same.
3. The particles will have more space between them as a liquid, but they will be moving faster as steam. At 100°C, the liquid water molecules are closer together, but in the gas phase, the steam molecules have greater kinetic energy, thus moving faster.
4. Particles will have more space between them and they will be moving at a higher speed as steam. This option encompasses both the increased spacing between particles in steam and their higher speed compared to liquid water at 100°C.
