Answer:

at T = 0ºC the change of state is from the solid state to the gaseous state

Explanation:

In this exercise we are asked about the changes of state, from the data we will assume that the material is water.

Water can exist in three solid states, liquid and gas, in a graph of pressure ℗ against temperature (T) there is a point called triple at T = 0.01ºC, below this point the curve has two states at high pressure solid and low pressure gas.

As a result of the previous ones at T = 0ºC the change of state is from the solid state to the gaseous state

<em> Frequency is perceived by humans as pitch; The sound intensity is the amplitude; Humans can only hear a specific range of sound, usually from 20 Hz to 20,000 Hz; The factors that go into a sound are its intensity, frequency and overtones (which are like interference, or background noises).</em>

When can liquid water remain above 100 C?
galben [10]
Well,

Typically, a substance is under 1 atmosphere of pressure, or 1 atm.  More than 1 atm means there is more pressure than that which the earth's atmosphere exerts on an object near the surface of the earth.

If a liquid is given enough energy, and the atmospheric pressure remains constant, the liquid will turn into a gas.  In the case of water, it will turn into water vapor at 100 °C.  However, if you increase the pressure to greater than 1 atm, the water will be pushed together, keeping it liquid.

Increase of green house gases, due to human activity, is warming the oceans. This causes changes in climate. Name three Earth sp
miskamm [114]
The three earth spheres which interact in this process are THE ATMOSPHERE, THE HYDROSPHERE AND THE BIOSPHERE.
The increase in the green house gases is destroying the ozone layers of the atmosphere, this makes it possible for more ultraviolet rays to penetrate through the atmosphere unto the earth surface. The increased temperature provided by these rays is warming up the oceans and this in turn is affecting the animals and the plants that reside in the oceans and those that depend on them. These chains of activities is changing the climate of the world and is affecting all the living things that live on the earth surface.
