Thermal conductivity was measured by the rapid transient technique using a thermal probe. The probe was inserted in the center of the sample for sufficient time so that the needle maintains temperature equilibrium with the sample and also sample in equilibrium with the surroundings. The temperature distribution generated in the sample was measured through digital micro-voltmeter which measured the voltage generated due to the rise in temperature at the probe situated in the sample. It was found that the effective thermal conductivity of Cucumis sativus (L.) ranged from 0.36 W/mK to 0.56 W/ mK when the temperature varied from 272 K to 298 K, however for Luffa acutangula L.), it is varied from 0.30 W/m K to 0.42 W/m K. It was also observed that near room temperature there was a fall in thermal conductivity with increasing temperature. Copyright@ International Science Community Association
