After a week, biochemical reactions in compost slow, and the temperature drops to 45 °C. The dark brown organic-rich mixture is ready for use in the garden. What is this temperature in degrees Fahrenheit? In kelvins? (3.3)

Verified step by step guidance

1. Start by converting the temperature from degrees Celsius to degrees Fahrenheit using the formula: \( F = \frac{9}{5}C + 32 \).
2. Substitute the given temperature in Celsius (45 °C) into the formula: \( F = \frac{9}{5} \times 45 + 32 \).
3. Calculate the result of the multiplication and addition to find the temperature in degrees Fahrenheit.
4. Next, convert the temperature from degrees Celsius to kelvins using the formula: \( K = C + 273.15 \).
5. Substitute the given temperature in Celsius (45 °C) into the formula: \( K = 45 + 273.15 \) and calculate the result.

Key Concepts

Temperature Conversion

Temperature can be expressed in different scales, primarily Celsius, Fahrenheit, and Kelvin. To convert Celsius to Fahrenheit, use the formula F = (C × 9/5) + 32. For Kelvin, the conversion is K = C + 273.15. Understanding these conversions is essential for accurately interpreting temperature readings in various contexts.

Biochemical Reactions

Biochemical reactions are processes that occur within living organisms, involving the transformation of substances through enzymatic activity. These reactions are temperature-sensitive, meaning that as temperature changes, the rate of these reactions can slow down or speed up, affecting the overall process, such as composting.

Composting Process

Composting is the natural decomposition of organic matter, such as food scraps and yard waste, facilitated by microorganisms. The process generates heat, which helps to break down materials, but as it progresses, the temperature can drop, indicating a slowdown in microbial activity. Understanding this process is crucial for effective gardening and soil enrichment.
