True or False
1. The pressure in temperature with depth known as geothermal gradient.
2. As the pressure is decreased, the melting temperature of materials is increased.
3. Volatiles are substances that cannot evaporates easily and can exist in gaseous form at the surface of Earth.
4. When volatiles mix wiht hot mantle rock, magma forms.
5. Rock's melting temperature increases when volatiles are introduced.

Please me .. thank you!!

Answer:

The first statement is true. The amount by which the Earth's temperature rises with depth is known as the geothermal gradient. It suggests that heat is moving from the Earth's interior to the surface. Every kilometer of depth results in an average temperature increase of about 25°C.

The second statement is also true. According to Boyle's Law, the temperature increases and the pressure decreases. This law states that pressure is inversely proportional to the volume of the gas at constant temperature and the number of moles and according to Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and the number of moles. Thus as temperature and volume are directly related, as temperature increase, the volume increase.

If a substance evaporates easily, it is said to be volatile and the property is called volatility. Thus, the third point is incorrect.

The hot mantle rocks when mixed with the lithosphere mantle, forms magma. The temperature of the earth as we go down increases. This increase in temperature will result in the melting of rocks beneath the layers and thus showing the property of volatility.
