List down two simple application of the first law of thermodynamics in our daily life?

1. Cooking: When we cook food, we are essentially applying the first law of thermodynamics. The heat energy from the stove or oven is transferred to the food, causing a change in temperature and ultimately cooking the food.

2. Exercise: When we exercise, our bodies convert chemical energy from food into mechanical energy to move our muscles. This process follows the first law of thermodynamics, as energy is neither created nor destroyed, but rather transformed from one form to another.

1. Cooking: When you cook food, you are applying heat to the food, which increases its temperature. This heat energy is transferred from the stove to the food, causing its molecules to move faster and break down. This process is an example of the first law of thermodynamics, which states that energy cannot be created or destroyed, only transferred or transformed.
2. Refrigeration: When you put food in the refrigerator, you are cooling it down by removing heat from it. The refrigerator uses a compressor to circulate refrigerant through its coils, which absorbs heat from the food and transfers it to the outside air. This process is also an example of the first law of thermodynamics, as the heat energy is transferred from the food to the refrigerator and then to the outside air.
