a student tested diet crispbreads in an investigation. The temperature rise per gram was 1.0°C. What is the ratio of temperatue rise caused by the crispbreads compared with:
a) The bread

b) the cheese

Respuesta :

A ratio is a relationship between two magnitudes or variables. Ratio crispbreads-bread is 1:2. Ratio crispbreads-cheese is 1:4.

What is a ratio?

A ratio is a quantified relationship between two magnitudes or variables. This relationship reflects their proportions.

The ratio can be calculated as a fraction -division- between them. It is a quotient between two related quantities.

The main goal is to measure and compare magnitudes or quantities more easily and objectively.

In the exposed example we know that,

  • 1 g of bread raises water temperature by 2 °C
  • 1 g of cheese raises water temperature by 4 °C

The ratio between them is 2:4 = 1:2

When comparing how a gram of bread and a gram of cheese raises water temperature, we can say that cheese raises water temperature by twice as bread does.

Now, we need to get the ratio of water temperature increase caused by crispbreads compared with bread and cheese.

We will proceed exactly as before. We need to compare the same mass of food (1 gram).

  • 1 g of bread raises water temperature by 2 °C
  • 1 g of cheese raises water temperature by 4 °C
  • 1 g of crispbreads raises water temperature by 1 °C

Ratio crispbreads-bread ⇒ 1:2 ⇒ bread raises water temperature twice more than crispbreads.

Ratio crispbreads-cheese ⇒ 1:4 ⇒ cheese raises water temperature by four times more than crispbreads.
