“…Thus, normalΔ T = T normalF − T normalC The energy gained as heat by the water is Q normalw normala normalt normale normalr = m normalw c normalw ( T F − T I , W ) where m w is the mass of water, c w is the specific heat of liquid water (4.18 J g –1 K –1 ), T I,w is the initial temperature of the water, and T F is the final temperature of the water. Similarly, the energy gained by the beaker is Q normalg normall normala normals normals = m normalg c normalg ( T F − T I , g ) where m g is the mass of the beaker, c g is the specific heat of glass (0.78 J g –1 K –1 ), T I,g is the initial temperature of the beaker, and T F is the final temperature of the beaker. It is noted that the beaker and water are at the same initial temperature ( T I,w = T I,g ).…”
