91Ó°ÊÓ

Compost can be made at home from grass clippings, kitchen scraps, and dry leaves. As microbes break down organic matter, heat is generated and the compost can reach a temperature of 155°F, which kills most pathogens. What is this temperature in degrees Celsius? In kelvins? (3.3)

Compost produced from decayed plant material is used to enrich the soil.

Short Answer

Expert verified

Therefore the temperature in Celsius is 68.3°Cand in Kelvin is341K.

Step by step solution

01

Equation.

Pathogens are killed by the temperature of the compost, which is 155°F. The following formula is used to compute the temperature in degrees Celsius:

For conversion, the temperature equation is employed as follows:

For conversion, use the following temperature equation:

TC=TF-321.8

02

Celsius.

The temperature in Celsius is TC, and the temperature in Fahrenheit is TF.

Substitute the value in equation,

role="math" localid="1651759830939" TC=TF-321.8

=155-321.8

=68.3°C

03

Temperature Equation.

The temperature of the compost, which is 68.3°C, is converted to kelvin as follows:

For conversion, the temperature equation is employed as follows:

role="math" localid="1651759606447" TK=TC+273

04

Kelvin.

TCdenotes the temperature in Celsius, while TCdenotes the temperature in Kelvin.

When you substitute in the above equation after rearranging it, you get:

TK=68.3+273

=341K
