Answer :
The temperature gradient shows the direction and rate of temperature change
The correct option that gives the temperature gradient between the two thermometers is option;
(3) 3 °C/m
Reason:
Known parameters are;
Temperature which the thermometer held at Δd = 2 meters above the floor shows, T₁ = 30°C
Temperature the thermometer on the floor shows, T₂ = 24°C
Required:
The temperature gradient between the two thermometers
Solution:
ΔT = T₁ - T₂
[tex]Temperature \ gradient = \dfrac{\Delta T}{\Delta d}[/tex]
Therefore;
[tex]Temperature \ gradient \ between \ the \ thermometers= \dfrac{30 ^{\circ}C - 24 ^{\circ}C}{2 \, m} = 3 \, ^{\circ}C /m[/tex]
The temperature gradient between the two thermometers = 3°C/m
Therefore, the correct option is option (3) 3°C/m
