While reading the temperature of body, only the bulb is immersed in it. The percentage error committed while calculating the length of the mercury column corresponding to a temperature rise Delta T°C, ignoring the expansion of glass bulb will be (volume expansivity of mercury is 182 xx 10^(-6)//°C and linear expansivity of glass is 8.3 xx 10^(-6)//°C )

1.	While reading the temperature of body, only the bulb is immersed in it. The percentage error committed while calculating the length of the mercury column corresponding to a temperature rise Delta T°C, ignoring the expansion of glass bulb will be (volume expansivity of mercury is 182 xx 10^(-6)//°C and linear expansivity of glass is 8.3 xx 10^(-6)//°C )
