Answer:

Whether matter exists as a solid, liquid or gas is determined by the arrangement of its particles and the strength of attraction between the particles. The three states can be easily distinguished because of their physical properties.

A physical property is a characteristic of matter which can be observed without any chemical change to the matter (shape, volume, colour, smell etc.). A chemical change is one in which new substance are formed.

Explanation:

Solids have <u>a fixed volume and shape</u>. They also vibrate in a fixed position. Ice

Liquids have <u>do not have a fixed shape but a definite volume</u>. They take the shape of their container. They are able to move past each other by allowing the liquid to flow. Water

Gases <u>do not have a fixed shape or volume</u>. Particles take up the space of the container they are in. Particles move freely and rapidly. Water vapour

someone has their blood tested and finds that their blood sugar level is 138. this is equivalent to 1.38%. How much glucose is i

disa [49]

The amount of glucose in each ml of their blood will be 0.00138 g.

<h3>Blood glucose concentration</h3>

The concentration of glucose in the person's blood is 1.38%.

This means that there is 1.38 g of sugar per Liter of blood.

1 Liter of blood contains 1.38 g of glucose, and there is 1000 mL in 1 Liter of blood.

1000 mL contains 1.38 g

1 ml contains = 1.38 x 1 / 1000 = 0.00138 g

This means 0.00138 g of glucose will be present in every 1 mL of the person's blood.
