The change in the water temperature of a bottle of water when it dropped by 4 degrees every hour is 48 degrees
<h3>What is temperature?</h3>
Temperature can be defined as the hotness or coldness of a thing or place.
To calculate the change in water temperature after 12 hours, we use the formula below.
Formula:
- ΔT₁₂ = 12t'................ Equation 1
Where:
- ΔT₁₂ = Change in the water temperature after 12 hours
- t' = drop in temperature per hour
From the question,
⇒ Given:
Substitute into equation 1
- ΔT₁₂ = 12×4
- ΔT₁₂ = 48 degrees
Hence, the change in the water temperature is 48 degrees
