Edna: [on Jack-Jack's suit] I cut it a little roomy for the free movement, the fabric is comfortable for sensitive skin... [a sheet of flame erupts in front of the suit] Edna: And it can also withstand a temperature of over 1000 degrees.
a typical hot pack is designed to reach a temperature of approximately 50 degrees Celsius starting from room temperature at about 20 degrees Celsius.Assume that the hot pack will contain 100.0 mL of water. typical hot pack is designed to reach a temperature of approximately 50 degrees Celsius starting from room temperature at about 20 degrees Celsius.
Assume a specific heat for thesolution of 4.18 J/g Â°C (same as water) and that the water in the cold pack is initially 23 Â°C. Show your calculations. 5. Using the same guidelines given for the cold pack, design a hot pack (using MgSO 4(s) that willreach a temperature of 60 Â°C.easuring heats of solution The heat of solution, â H soln, is the heat that is generated or absorbed when a salt is dissolved in water and is expressed in kJ/mol solute. â H soln is negative for an exothermic solution process and positive if it isendothermic.
