at what temperature would the MP speed of H2 be twice than at 40 degree Celsius Share with your friends Share 0 Aastha Bishnoi answered this Dear student We know the formula for most probable speed Cmp is 2.R.TM 40 degree celsius= 40+ 273=313 KLet Cmp be x at 313 K at temperature T = t K , Cmp = 2x , so,2R×313M =X22R×313M =2XSINCE, R and M remains constantso, t= 4×313 K =1252K1252-273= 979 degree celsiusRegards 2 View Full Answer
