Given : The temperatures of two bodies measured by a thermometer are t₁ = 20ᵒC ± 0.5ᵒC and t₂ = 50ᵒC ± 0.5ᵒC.
To Find : The temperature difference t = t₂ – t₁
Explanation:
t₁ = 20ᵒC ± 0.5ᵒC
t₂ = 50ᵒC ± 0.5ᵒC.
temperature difference t = t₂ – t₁
t = (50 - 20)°C ± (0.5 + 0.5)°C
( Errors/Tolerances are always added up , when u add or subtract term ) .
=> t = 30°C ± 1°C
The temperature difference t = 30°C ± 1°C
