Answer:

Polar bears have become a symbol of global warming, because the Arctic landscape is one of the first to absorb the impact of rising temperatures. Warming temperatures melt polar ice and force animals like the polar bear to move farther south in search of food and other resources.

If variable A decreases, how will variable B respond?

wel

Variable B will become lower due to variable A becoming smaller think of it like a seesaw if you put something on one side there will be a reaction on the other =)

A two-liter soft drink bottle can withstand apressure of

larisa86 [58]

Explanation:

According to the ideal gas equation, PV = nRT.

where, P = pressure, V = volume

n = no. of moles, R = gas constant

T = temperature

Also, density is equal to mass divided by volume. And, no. of moles equals mass divided by molar mass.

Therefore, then formula for ideal gas could also be as follows.

P = $\frac{mass}{volume \times molar mass} \times RT$

or, P = $\frac{density}{\text{molar mass}} \times RT$

Since, density is given as 0.789 g/ml which is also equal to 789 g/L (as 1000 mL = 1 L). Hence, putting the given values into the above formula as follows.

P = $\frac{density}{\text{molar mass}} \times RT$

= $\frac{789 g/l}{46.06 g/mol} \times 0.0821 L atm/mol K \times 373 K$

= 525 atm

As two-liter soft drink bottle can withstand a pressure of 5 atm and the value of calculated pressure is 525 atm which is much greater than 5 atm.

Therefore, the soft drink bottle will obviously explode.

Water molecules form hydrogen bonds to help in the process of water transport. Which property of water is described?

AlekseyPX

The property of water which is described in the lines above is cohesion.
It refers to the fact that water molecules stick to other water molecules, i. e. to themselves, as opposed to sticking to another material, which happens with adhesion. Water and capillaries don't have any connection.
