What if there was an inverse relationship between the temperature and the volume? How do you think the world might be different?
kari74 [83]

If there was an inverse relationship between the temperature and the volume, our daily lives change because in high temperature things will contract.

<h3>What if there was an inverse relationship between the temperature and the volume?</h3>

If there was an inverse relationship between the temperature and the volume then with increasing temperature decrease occur in the volume of a substance. If this type of relationship is present in the world, the objects will contract when the temperature is high and expand when the temperature is low which make the solid materials expand at winter and contract at summer season.

So we can conclude that if there was an inverse relationship between the temperature and the volume, our daily lives change because in high temperature things will contract.

The temperature of 75 mL of gas is decreased from 450 K to 150 K while the pressure is held constant. What is the new volume of
irinina [24]

Answer: Option A) 25mL

Explanation:

Given that,

Original volume of gas (V1) = 75mL

Original temperature of gas (T1) = 450K

New volume V2 = ?

New temperature T2 = 150K

Since volume and temperature are given while pressure is held constant, apply the formula for Charle's law

V1/T1 = V2/T2

75mL/450K = V2/150K

To get the value of T2, cross multiply

75mL x 150K = 450K x V2

11250mL•K = 450K•V2

Divide both sides by 450K

11250mL•K / 450K = 450K•V2/450K

25mL = V2

Thus, the new volume of the gas is 25mL

Briefly explain the benefits and consequences of technology.
Elza [17]
Well there are plenty of benefits and consequences.

But one would be the ability to do certain tasks without actually having to do them. A consequence could be on the environment. For example, the use of a car plays a big part on the environment involving smog.

Hope this helps!
