Question

At a temperature of 273 Kelvin of ice and water the specific sizes are 1.089 and 1.0 mg, respectively. The molecular melting heat of ice at a temperature of 273 Kelvin and pressure of 1 bar is 6.025 kJ mol-. If melting 90 grams of ice at a temperature of 273 Kelvin and 1 bar of pressure becomes water of the same temperature, calculate the ∆H and ∆U values ​​for that process. (1 liter bar = 101.32 joules)


plz ans this que as soon as possible..​

Answer 1
