I'll give you an example, Rub your hands together. Then touch your face or leg to feel any temperature change. Most likely your hands are warmer.
7 is neutral on the pH scale
Answer:
Properties describe physical matter.
Explanation:
Boyle's law gives the relationship between pressure and volume of gas.
for a fixed amount of gas, at constant temperature the pressure of gas is inversely proportional to its volume.
PV = k
where P - pressure, V - volume and k - constant
P1V1 = P2V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side.
substituting the values in the equation
1.2 atm x 1.0 L = P x 4.0 L
P = 0.3 atm
new pressure is 0.3 atm
