of the metal was determined by the heat energy calculations. The heat capacity that was found matched closely to that of the lead. There were several possible sources of error that could be found throughout the lab. Some of the main errors as seen in question 7 that could have affected the results of the lab were the amount of water transferred with the hot metal‚ the metal cooling off as it was transferred from the calorimeter‚ the calorimeter lost heat to the surroundings as it was stirred

Heat exhaustion and heatstroke As days slowly begin to heat up it is important to stay cool and keep hydrated across the screaming scorching sun. Summer time usually means longer days and if you live close to the equator you know about the 100+ degree weather that comes with it. Without the proper precautions you could easily fall to heat exhaustion or far worse a heat stroke. Athletes are more prone to this type of sudden illnesses because of the constant running and exercise they do on a daily
