What is the final temperature (in ˚C) of a 2.91 kg glass baking dish if it was heated from a starting temperature of 23˚C by 775 kJ of heat [round your final answer to zero decimal places]? {specific heat of glass = 840 J/(kg∙˚C)}

An unknown hot metal at 148.7°C with a mass of 49.6g was mixed with 28.61g of water at an initial temperature of 19.74°C.  A final temperature (for both water and metal) of 27.71°C was reached. In units of J/(g°C), what is the specific heat of the unknown metal?  Note: In the space below, please enter you numerical answer.  Do not enter any units.  If you enter units, your answer will be marked as incorrect.

An ordinary drinking glass is filled to the brim with 350 mL of water at 100.0 "C. If the temperature is decreased to 20.0 °C, then what volume of water could be added to the glass? The coefficient of volume expansion for glass is 27.0x108 (C)¹. The coefficient of volume expansion for water is 210 x 10-6 (C)1. 'n Gewone drinkglas is tot heelbo gevul met 350 mL water by 100.0 "C. Watter volume water kan by die glas gevoeg word indien die temperatuur tot 20.0 °C daal? Die volume uitsettingskoeffisiënt van glas is 27.0x 10- (C)¹.
