Apply sunscreen with a high SPF to protect your skin from UV (ultraviolet) rays
Answer:
a) The heat which we supply to water during boiling is used to overcome these forces of attraction between the particles so that they become totally free and change into a gas. This latent heat does not increase the kinetic energy of water particles and hence no rise in temperature takes place during the boiling of water.
b) Steam produces more severe burns than boiling water even though both are at 100oC because steam contains more heat, in the form of latent heat, than boiling water.

Answer:
NH3 , SO3 , BF3
Explanation:
trigonal planar = AB3 ------------> Coordination number = 3
for example = NH3 , SO3 , BF3
all of them are trigonal planar
1: their dna is found in the nucleiod
2: their cell wall acts as an area of protection, helps to maintain shape and prevent dehydration.
Answer:
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
