<span>Which part of the electromagnetic spectrum has a higher frequency than ultraviolet light? </span>B. Gamma Rays.
Answer:
Viscosity of water decreases markedly with increasing temperature. When the viscosity decreases, the flow resistance decreases. So for the same driving force, that is the pressure drop per unit length, the water flow rate will be higher.
Hope this helps :)

Answer: 1 mole of 
has the greatest mass.
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP , contains avogadro's number 
of particles and weighs equal to the molecular mass of the substance.
1 mole of has a mass of 40 g.
1 mole of 
has a mass of 28 g
1 mole of 
has a mass of 32 g
1 mole of 
has a mass of 16 g.
1 mole of 
has a mass of 30 g.
Thus the greatest mass is of 1 mole of
