The video discusses how to solve a sample calorimetry calculation.
The process of measuring the heat released in any type of reactions like chemical and physical reactions. This is the definition of calorimetry. It is measured by calorimeter.
Example: tourism industry Cwater = 4200 J/kgK cice = 2100 J/kgK ccopper = 390 J/kgK Lf, ice = *105 J/kg Lv, water = *105 J/kg Latent heat and Specific heat capacity questions. 1. How much water at 50 C is needed to just melt kg of ice at 0 C? 2. How much water at 32 C is needed to just melt kg of ice at -10 C? 3. How much steam at 100 is needed to just melt 5 kg of ice at -15 C? 4. A copper cup holds some cold water at 4 C. The copper cup weighs 140g while the water weighs 80g. If 100g of hot water, at 90 C is added, what will be the final temperature of the water? How much water at 32°C is needed to just melt 1.5 kg of ice at -10°C? 3. How much steam at 100° is needed to just melt 5 kg of ice at -15°C? 4. A copper cup holds some cold water at 4°C. The copper cup weighs 140g while the water weighs 80g. If 100g of hot water, at 90°C is added, what will be the final temperature of the water? Tags:Information
