ICSE Class 10: Change of Phase and Latent Heat Videos | Calorimetry

• what amount of water at 40 degree celsius is to be mixed with 250 grams of ice at 10 - 10 degree Celsius so that equally premium temperature is 25 degree Celsius
• A piece of ice of mass 40g is added to 200g of water at 50 degree celcius
• a calorimetry of mass 50g contains 200g of water at 30degree celcius . Calculate the final temperature of the mixture when 40g of ice at -10degree celcius is added to it.
• find result of mixing 10g of ice at-10c of water at 10c
• Is heat a conserved quantity? Give reason in suport of your answer?  
• The temperature of 170g of water at 50degree celsius is  lowered to 5degree celcius by adding certain amount of ice to it.Find the mass of ice added . (Take ,specific heat capacity of water=4200J/kg0c and specific latent heat of ice =36000J/kg)
• Water falls from a height of 50m. Calculate the rise in the temperature of water when it strikes the bottom. G=10ms-2 C=4200J/Kg°C
• Detail solutions
