Question

1.      What is the temperature rise from -18°C to -11°C?​

Answer 1

Answer:

The Celsius and Kelvin scales increase by the same increments, meaning that to increase the temperature by 1°C results in the same increase of 1 K. The major difference is that when water freezes, a Celsius thermometer will read 0°C, and a Kelvin thermometer will read 273.15 K. The scales differ by 273.15.

Answer 2

Answer:

7°C

Step-by-step explanation:

Simple just find the difference of the two number from the greatest to smallest.

Here is a tip,

As negative numbers = the smaller numbers are greater, the greater numbers                        are smaller

So, -11 degrees is greater that -18 degrees

And also will be helpful with the use of brackets,

( - 11 ) - ( - 18 )

- 11 + 18                                                               ( 2 negative signs cancel)

So, the answer is 7°C
