Answer:

Bro.

Mercury – 1,516mi (2,440km) radius; about 1/3 the size of Earth.

Venus – 3,760mi (6,052km) radius; only slightly smaller than Earth.

Earth – 3,959mi (6,371km) radius.

Mars – 2,106mi (3,390km) radius; about half the size of Earth.

Jupiter – 43,441mi (69,911km) radius; 11x Earth's size

The volume of a gas is 450 mL when its pressure is 1.00 atm. If the temperature of the gas does not change, what is the

NikAS [45]

Answer: 0.225 atm

Explanation:

For this problem, we have to use Boyle's Law.

Boyle's Law: P₁V₁=P₂V₂

Since we are asked to find P₂, let's manipulate the equation.

P₂=(P₁V₁)/V₂

$P_{2} =\frac{(1.00atm)(0.45L)}{2.00L}$

With this equation, the liters cancel out and we will be left with atm.

P₂=0.225 atm

Convert -12.00 degrees Celsius to the unit Kelvin. 296.15 K 261.15 K -285.15 K -162.85 K

Gre4nikov [31]

To convert Celsius to kelvin, we need to know the formula. Kelvin = Celsius + 273.15. Now, we can figure out how many degrees kelvin -12 degrees Celsius is.

Kelvin = -12 + 273.15

Kelvin = 261.15

A 365 L balloon is blown up inside at 283 K. It is then taken outside in the hot sun and Heated to 300K. What is the new volume?

asambeis [7]

V₁ = initial Volume of the balloon after it is blown up = 365 L

V₂ = new Volume of the balloon after it is taken outside = ?

T₁ = initial temperature of the balloon = 283 K

T₂ = new temperature of the balloon = 300 K

using the equation

V₁/V₂ = T₁/T₂

365/V₂ = 283/300

V₂ = 387 L
