Infer if the mineral Talc would be a good choice when building a statue outside?

ruslelena [56]

Talc is not a good choice when building a statue because the mineral Talc is one of the weakest minerals on the Mohs Scale with a hardness of 1 since it could be scratched by a fingernail, which means that when people build a statue with Talc, it could be easily broken down.

LINK Relating Volume and Absolute Temperature

natulia [17]

The volume is reduced to 8.5 L.

<u>Explanation:</u>

According to Charles law, the gases has the tendency to expand on heating, and so the volume of the gases increases on increasing the temperature which is measured in Kelvin, and also the volume and temperature are in direct proportion.

Given that:

V1 = Volume 1 = 10 L

T1 = Temperature 1 = 295 K

V2 = ?

T2 = Temperature 2= 250 K

Now Charles law can be mathematically expressed as,

$$\frac{V1}{T1} = \frac{V2}{T2}$

We can rearrange the equation to find V2 as,

$$ V2= \frac{V1\times T2}{T1}$

$$ V2 = \frac{10 L \times 250 K}{295 K} = 8.5 L$

Thus we obtain the volume V2 = 8.5 L which is low when compared to Volume 1 so we can conclude that the volume has reduced
