Answer is gas for sure and I think it’s ice for question 2
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Answer:
The coefficient of thermal expansion α is

The coefficient of compressibility

Now considering 
From equation (1) we have that

From ideal equation

So

=> 
=> 
Explanation:
From the question we are told that
The coefficient of thermal expansion is 
The coefficient of compressibility is 
Generally the ideal gas is mathematically represented as

=> 
differentiating both side with respect to T at constant P

substituting the equation above into 


Recall from ideal gas equation 
So

Now differentiate equation (1) above with respect to P at constant T

substituting the above equation into equation of 


Recall from ideal gas equation that

So

Now considering 
From equation (1) we have that

From ideal equation

So

=> 
=>
