Steel because of friction. When rubber moves over smooth surfaces, it's the molecular forces between the two that are the main cause of friction. But when the surface is rough, it's the deformation of entire molecular layers of rubber that's the chief cause of friction.

Andreyy89

Answer:

49.35  mL

Explanation:

Given: 56.2 mL of gas

To find: volume that 56.2 mL of gas at 820 mm of Hg would occupy at 720 mm of Hg

Solution:

At 820 mm of Hg, volume of gas is 56.2 mL

At 1 mm of Hg, volume of gas is \frac{56.2}{820}

At 720 mm of Hg, volume of gas is \frac{56.2}{820}(720)=49.35\,\,mL
