If the required pressure in the tyre of a car is 199 kPa then

(i) what is the gauge pressure?

(ii) what is the absolute pressure?

# If the required pressure in the tyre of a car

(i) Gauge pressure

${ p }*{ g }$ = 190 k Pa
(ii) Absolute pressure
p = ${ p }*{ a }$ +

${ p }_{ g }$ = 101k Pa + 199k Pa = 300k Pa
