solve questions 5,6,7,8,9 and 10
Answers
answer V - when we heat a illiquid it doesn't change its temperature because because because this increase the kinetic energy of the particles and this the particles start shaking and this heat is used for overcoming the force of attraction therefore called the latent heat of vaporization
answer 6th ‐ not knowing the answer
answer 7th - the temperature at which a particular substance short burning this is known as boiling point of the temperature where as the melting point is the temperature at which a substance start melting for for water melting point is zero degree celsius whereas boiling point is 100 degree Celsius
answer 8th- friendly light or burgundy incense stick it increase its kinetic energy and diffusion takes place faster and therefore it diffuse with the air and reaches few metres away to us and this spreads all over the room
answer 9th- steam gives more severe burns because it has more kinetic energy or latent heat it give us more heat in order to change its state from gas to liquid
answer 10th- naphthalene balls are disappear when they are exposed to air because they are supplied material and therefore the process of sublimation takes place and their directly change a solid to gas
if this was helpful then please given like and markers brainliest answer thank you
Answer: 5
Explanation:the amount of heat required to content unit mass of liquid into its vapour state without change in its temperature called is latent heat of vaporization the latent heat of vaporization of water is 540 c a l / g / °C
