Explain with AI

In given figure a silicon diode is carrying a constant current of 1 mA1 \mathrm{~mA}. When the temperature of the diode is 20∘C,VD20^{\circ} \mathrm{C}, \mathrm{V}_{\mathrm{D}} is found to be 700  mV700 \; \mathrm{mV}. If the temperature rises to 40∘C,VD40^{\circ} \mathrm{C}, \mathrm{V}_{\mathrm{D}} becomes approximately equal to
