A bike tire at a pressure of 740 mmHg and a temperature of 290 K has a volume of 2.2 liters.
A child gets on the bike and rides it outside.
What is the new pressure if the temperature
outside is 296 K and his weight causes the tire's
volume to drop to 2.0 liters?

The new pressure is 831 mm Hg

Explanation:

The combined gas equation is,

where,

= initial pressure of gas = 740 mm Hg

= final pressure of gas = ?

= initial volume of gas = 2.2 L

= final volume of gas = 2.0 L

= initial temperature of gas = 290 K

= final temperature of gas = 296 K

Now put all the given values in the above equation, we get:

The new pressure is 831 mm Hg

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

thats a little if u want the answer just look it up on google thats what i do haha : )
