Answer:
because gas molecules have more kinetic energy and are smaller than liquid molecules. diffusion in liquids is slower because the particles in a liquid move more slowly. it happens faster if the temperature is increased
Answer:
8) A hanging 7.5 kg object stretches a spring 1.1 m. What is the spring constant? 1 . 1 66. 82 NIMO 9) A spring has a constant of 875 N/m. What hanging mass will cause this spring to stretch 4.5 m? Iouliply then divide 875 X 4. 2- - (4 04. 7919) 10) A spring with a spring constant of 25 N/m is stretched 65 cm. What was the force used? 11) A 25 N force stretches a spring 280 cm. What was the spring constant? 12) A 75 N force stretches a spring 175 cm. What was the proportionality constant? 8) 66.82 N/m 9) 401.79 kg 10) 16.25 N 11) 8.93 N/m 12) 42.86 N/m

Solids are just vibrating and they cannot move past each other
the liquids they move freely and move past each other
Answer:
The SI unit for length is meters(m), for mass is kilograms(kg)
