Answer:
faster, and the ingredient will be a liquid.
Explanation:
Answer:
A) 6.15×10^14 per sec
B)2.5 sec
Explanation:
Wavelength of light = 488 nm
speed of light = 3×10^8 m/s
therefore, frequency of light 
⇒ 
⇒ν= 6.15×10^14 per sec
b) distance between moon and earth = 3.8×10^5 km.
= 3.8×10^8 m
light travel from earth moon and back to earth
therefore, distance traveled= 2× 3.8×10^8 m = 7.6×10^8 m
therefore time= distance/speed
⇒ time= 
= 2.5 sec
So, for a round trip time required is 2.5 sec.

Answer - Inter-molecular attractions
Explanation-
As we know everything around us is made up of matter that means everything has molecules as their basic structure. The state of anything is decided by the spaces between the molecules.
The state of the objects that have strong inter-molecular attractions a solid and gradually the lesser will be in state of liquid and gas. The attraction between the molecules is overcome only when a certain amount of energy is provided from outside.
