Answer:

38.75KPa

Explanation:

The following were obtained from the question:

V1 = 155cm^3

P1 = 22.5kPa

V2 = 90cm^3

P2 =?

The new pressure can obtain by doing the following:

P1V1 = P2V2

22.5 x 155 = P2 x 90

Divide both side by 90

P2 = (22.5 x 155) /90

P2 = 38.75KPa

Which type of model is a way of imagining how something works?​
RUDIKE [14]

Answer:

mental model is an explanation of someone's thought process about how something works in the real world. It is a representation of the surrounding world, the relationships between its various parts and a person's intuitive perception about his or her own acts and their consequences. Mental models can help shape behaviour and set an approach to solving problems (similar to a personal algorithm) and doing tasks.
