Lipase is used in biological detergents. During South Alrican summers, the average temperature of cold tap water is \( 25^{\circ} \mathrm{C} \) and the average for wamm tap water is \( 55^{\circ} \mathrm{C} \). Explain Two reason why it is recommended that biological detergents bo Lsed with cold water.

Using biological detergents with cold water is recommended for several reasons: 1. **Enzyme Activity**: Biological detergents contain enzymes, such as lipase, which are effective at breaking down stains and dirt at lower temperatures. Cold water (around \( 25^{\circ} \mathrm{C} \)) helps maintain the stability and activity of these enzymes. Higher temperatures, like \( 55^{\circ} \mathrm{C} \), can denature the enzymes, reducing their effectiveness and potentially leading to a loss of cleaning power. 2. **Energy Efficiency**: Washing clothes in cold water is more energy-efficient compared to using warm water. Heating water consumes a significant amount of energy, which can lead to higher utility bills and increased environmental impact. By using cold water, consumers can save energy and reduce their carbon footprint while still achieving effective cleaning with biological detergents. In summary, using cold water preserves enzyme activity and promotes energy efficiency, making it a practical choice for laundry with biological detergents.
