How does endothermic reaction work

WebSep 16, 2024 · A reaction or process in which heat is transferred to a system from its surroundings is endothermic. The first law of thermodynamics states that the energy of the universe is constant. The change in the internal energy of a system is the sum of the heat transferred and the work done. WebPour ½ cup of tap water into a cup. 2. Stir the cup with a thermometer and record the temperature. 3. Add four teaspoons of sodium bicarbonate to the water and stir with the thermometer. Record the resulting temperature. 4. Subtract the temperature from Step 2 from the temperature in Step 3. This will give you the change in temperature.
