Alenkinab [10]

Answer:

25.04 g is the mass of pentane

Explanation:

Pentane density = Pentane mass / Pentane volume

1 cm³ = 1mL

0.626 g/mL = Pentane mass / Pentane volume

0.626 g/mL = Pentane mass / 40 mL

0.626 g/mL . 40 mL = Pentane mass → 25.04 g

Ocean currents determine the various directions of wind movement.

<h3>What is ocean current?</h3>

Ocean currents are caused by differences in density as well as the temperature of the moving winds across the ocean. In the ocean, warm water is found at the top while cooler water occurs far below.

Warm ocean currents originate near the equator and move towards the poles. The ocean currents control the direction of winds in an area.

A 1500 L weather balloon is at 'a temperature of 290 K on the ground. As it rises the
myrzilka [38]

Answer:

1086.2 L

Explanation:

The computation of the volume of the elevation is given below:

Here we assume the volume of the elevation be x

As we know that

V¹ ÷ T¹ = V² ÷ T²

Here

V^1 = 1500

T^1 = 290

V^2 = x

T^2 = 210

Now place these values to the above formula

So,  

1500 ÷ 290 = x ÷ 210

x = 1086.2 L
