Question

About A has a molar mass 1/4th that of molecule B. If me has aroor mean-square speed vms of 1000 m/s at 50 °C, then the sed for mobile A at the same temperature is: Salone a 4000 ms a 1000 ms 2000 m's Od 500 ms F e 250 m's T

Answer 1

Solution 4 Rooit - mean-square Vremo 3RT M velocity is given by where Ris gas consultant Temperature M = molar mass. = 1.000m/5 , T- 50°C = 323K. For molecule B , Vrms om lood mis = 3RT M Por molecule A T=50°C = 323k. m = 1 m 4 A Viens 3 RT 2 BRT om Nm diding equation is by 6) A 2 Vems 1000 4 - 2000 mis Vrms This is option c. solution 5 specific heat is the heat given to the of material to raise wait temperóture. So, for Gold Cgold = 126 ] 1 kg K. it means I kg of gold meeds 126 Joule of energy to raise its temperature by 1 K unit mass

for glass Cores mean 5 I kelvin. = 840 J kg k 1 kg of Glass needs 840 Joules of energy to raise its temperature by Suppose we gove 2000 J of energy to both the temperature of gold will rise by (-1000/126 7.9 MBK, while for glass (1000/80 =) 4.19K. So, gold will have higher temperature option Solution 67 Temperature is system how much body Heat is the energy transfer between two bodies of different temperature in the form of thermal energy This is option c. This is a. а to measure cold or hoit b IS a
