• 
• 
• NONE ON THE ABOVE

THE TRANSFER OF HEAT GENERALLY REQUIRES MEDIUM BUT THERE IS ONE METHOD OF HEAT TRANSFER WHERE THERE IS NO NEED OF ANY MEDIUM.NAME THE METHOD

• CONDUCTION

• RADIATION

• CONVECTION

• ALL OF THE ABOVE

BECAUSE OF LOW PRESSURE ON OCEAN RAINFALL TAKES PLACE .LOW PRESSURE IS CREATED IN THE ATMOSPHERE DUE TO SUN. NAME THE METHOD OF HEAT TRANSFER IN THIS CASE.

• CONDUCTION

• CONVECTION

• RADIATION

• NONE OF THE ABOVE

THERE ARE TWO BEAKERS WITH HOT AND COLD WATER.THE TEMPERATURE OF HOT WATER IS 60^oc and the that of cold water is 10^O C.WHEN WATER IN TWO BEAKERS IS MIXED IN THIRD BEAKER.THEN THE TEMP.OF THIRD BEAKER WILL BE
