Answer:
-17 < -1
Step-by-step explanation:
obviously -1 is greater than -17
< means less than and
> means greater than
therefore we are saying
-17 is less than -1
The pressure is 38.5 Newton per square meter (N/m²)
<h3>What is temperature?</h3>
Temperature can be defined as the quantity that is used to measure the degree of hotness or coldness of a body in °Kelvin or ° Celsius.
When the pressure of a glass varies directly with the temperature, this means that once there is an increase in temperature there should be an increase in pressure of the medium too.
To calculate the new pressure the gas formula is used;
Where,
P1 = 18.9N/m²
T1 = 90k
V1 = 20m³
T2 = 110k
V2 = 12m³
P2 = X
P1V1/T1 = P2V2/T2
Make P2 the subject of formula;
P2 = P1V1T2/T1V2
P2 = 18.9×20×110/90×12
P2 = 41580/1080
P2 = 38.5 N/m²
