in two beaker 50 ml water of about 70 degree Celsius it is taken . In beaker A 50 ml of water of about 30 degree Celsius and after 5 minutes. In beaker 30 degree Celsius is added. what would observe is the temperature of both beakers recorded immediately? Why ? |

Answer» Rate of heat flow from higher temperature to lower temperature.Rate of heat of transfer between two hot or cold body depends upon the temperature difference between them. That mean higher the difference higher will be heat transfer rate from hotter to colder body. In Beaker A Temperature difference is 20C But Beaker B is placed in open area so it wil cool down itself in 5 minute and when we add water the temperature difference would be less than 20C So Beaker A will cool down itself rather than Beaker B because of higher temperature difference. So temperature of B will be greater than as that of A |
