An automobile gasoline tank holds 25.0 gal when full. how many pounds of gasoline will it hold if the gasoline has a density of
lora16 [44]

The amount (in pounds) the gasoline tank will hold when full is 153.76 lb

<h3>What is density? </h3>

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

<h3>How to convert gallon to milliliters </h3>

1 gallon = 3785.412 mL

Therefore,

25 gallon = 25 × 3785.412

25 gallon = 94635.3 mL

<h3>How to determine the mass </h3>
  • Density = 0.737 g/mL
  • Volume = 94635.3 mL
  • Mass =?

Mass = Density × Volume

Mass = 0.737 × 94635.3

Mass = 69746.2161 g

<h3>How to convert grams to pounds </h3>

453.592 g = 1 lb

Therefore,

69746.2161 g = 69746.2161 / 453.592

69746.2161 g = 153.76 lb

When a distance between gas particles increases, the volume of the gas increases true or false??​
Studentka2010 [4]

It is true that when a distance between gas particles increases, the volume of the gas will also increase.

Answer: Option A

<u>Explanation:</u>

The volume of any material can be the space occupied by any material. And the space required by any material to occupy a desired shape or size is determined by its bonding and distance between the particles making that material. If the particles which are soft and small can be compressed easily to occupy very small volume compared to compound made up of hard and large particles.

Along with this, the distance between the neighbouring particles also play a major role, as if we consider a laddo, we can compress it to small size by reducing the distance between neighbouring particles while we will not be able to compress the size or volume occupied by a table as we cannot reduce the distance of particle separation. Thus, it is true that if the distance between gas particles increased then the volume of gas particles will also increase.
