Question

room temperature of a room 30 degrees celsius and decreasing at rate of 5 degrees celsius for over find room temperature of 5 hours ??? please tell me answer ​

Answer 1

Answer:

the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

Answer 2

Answer:

Since there is a decrease in temperature by 5°C every hour, let's first find the total decrease in 10 hours:

or, 10 × 5 = 50°C.

This means that after 5 hours, there is going to be a decrease in temperature by 50°C.

Since 'decrease' refers to the subtraction operation, let's find the total decrease in temperature from the initial temperature of 40°C as:

or, 40 - 50 = -10°C.

Therefore, the room temperature 5 hours after the process begins is -10°C.
