Explain how to calculate heat gained by a calorimeter if the heat lost was -2654.3 J and the heat gained was 3030.5 J. What is the heat capacity of a conductive calorimeter ? Calculate the energy needed to heat a cube of copper with a volume of 13.0 cm3 from 15 degrees Celsius to 27...
Using basic theory and this calculator, you can quickly find the answers to the specific heat equation by solving for any variable in any units. Heat capacity or thermal capacity is a measurable physical quantity equal to the ratio of the heat added to (or removed from) an object to the ...
From the perspective of the cooling pad, heat is gained from the ceramic strip over the entire pad domain. This can be modeled by a heat source term in the equation (25). Due to the law of energy balance, the heat source of the pad should have the same magnitude but an opposite sign...
from the warmer material travels to the cooler one as soon as they come into touch. This continues until the temperatures of materials A and B are equal. The heat gained by the colder substance is equivalent to the heat lost by the warmer one, according to the law of conservation of ...
However, these changes can be lost at nearly the same rate that they are gained. Workers who do not continue to have periodic heat exposures will experience diminished acclimatization after several days, and may lose about 75% of their acclimatization within about 3 weeks (CHPPM, 2003). ...
Heat lost by mercury = heat gained by water. 3.39kg x 139J/kg/C x (243-100) = 0.476kg x 4186J/kg/C x (100-10) + 22.6x10^5 J/kg x m m= 2.1 x 10^-5kg is what I get which is the wrong answer. Where have I gone wrong? Physics news on Phys.org Advanced atom ...
Calculate the heat that is either gained or lost when 25.0 g of steam (MW = 18.02, cp = 0.0753, Delta Hfus = 6.01 kJ, Delta Hvap = 40.67 kJ) at 100 degrees C condenses to liquid water at 100 degrees C How much heat is needed to convert 8.75 g of 100 d...
the heat gained by the water When 10 kcal of heat is added to 2.0 kg of a substance, its temperature increases 20 degree C. What is the specific heat of the substance? Calculate the energy released when cooling 10 g of water fr...
