How many kilocalories of heat would be needed to melt 0.12kg of ice at 0 degrees c and increase the temperature to 25 degrees c?

To calculate the total kilocalories needed, first, you need to melt the ice. The latent heat of fusion for ice is approximately 80 kcal/kg, so melting 0.12 kg of ice requires 0.12 kg × 80 kcal/kg = 9.6 kcal. After melting, you need to raise the temperature of the resulting water from 0°C to 25°C. The specific heat of water is about 1 kcal/kg°C, so heating 0.12 kg of water by 25°C requires 0.12 kg × 25 kcal/kg°C = 3 kcal. Therefore, the total heat needed is 9.6 kcal + 3 kcal = 12.6 kcal.

WHY is It more important in terms of reaction rate to take groceries straight home from the store when it is 25 degrees c than when it is 2 degrees c?

The reaction rate of food spoilage and microbial growth is significantly higher at 25 degrees Celsius compared to 2 degrees Celsius. At warmer temperatures, bacteria and enzymes are more active, leading to faster deterioration of perishable items like dairy, meat, and produce. Therefore, taking groceries straight home at 25 degrees helps maintain their safety and quality, while a cooler temperature slows down these processes, allowing for more time before spoilage occurs.

Do i need to wear a jacket if it is 8 degrees Celsius outside?

Will increase the volume of a gas Decreasing the pressure applied to the gas Decreasing the number of gas molecules Decreasing the size of the gas molecules Decreasing the temperature?

Increasing the volume of a gas is typically achieved by decreasing the pressure applied to it, as per Boyle's Law, which states that volume is inversely proportional to pressure at constant temperature. Decreasing the number of gas molecules would also lead to a decrease in pressure, potentially allowing for an increase in volume if the container size remains constant. However, decreasing the size of the gas molecules or the temperature would not directly lead to an increase in volume; in fact, decreasing temperature generally reduces the volume of a gas.
