10-2.Transmission of Heat
medium

$20cm$ લંબાઇ ધરાવતા સળિયાના છેડાના તાપમાન $ {100^o}C $ અને $ {20^o}C $ છે.તો મધ્યબિંદુનું તાપમાન...... $^oC$

A

$50$

B

$60$

C

$40$

D

$30$

Solution

(b) Temperature gradient $ = \frac{{100 – 20}}{{20}} = 4^\circ C/cm$

temperature at centre $ = 100 – 4 \times 10$ = $60°C$
