Question

According to Zeroth law of thermodynamics, if two systems A and B are separately in equilibrium with C, then (A) TA=TB (B) TA>TC, TB>TC and TA=TB (C) TA=TC and TA ≠ TB (D) TA < TC, TB < TC and TA = TB

According to Zeroth law of thermodynamics, two systems in thermal equilibrium with a third system separately are in thermal equilibrium with each other.
So, if

A

and

B

are separately in equilibrium with

C

, then

T_{A} = T_{C}

and

T_{B} = T_{C}

.
This implies that

T_{A} = T_{B}

, i.e. the systems

A

and

B

are also in thermal equilibrium.

Q. According to Zeroth law of thermodynamics, if two systems $A$ and $B$ are separately in equilibrium with $C$ , then

$T_{A} = T_{B}$

$T_{A} > T_{C}, T_{B} > T_{C}$ and $T_{A} = T_{B}$

$T_{A} = T_{C}$ and $T_{A} \neq = T_{B}$

$T_{A} < T_{C}, T_{B} < T_{C}$ and $T_{A} = T_{B}$

Q. According to Zeroth law of thermodynamics, if two systems A and B are separately in equilibrium with C, then

TA​=TB​

TA​>TC​,TB​>TC​ and TA​=TB​

TA​=TC​ and TA​=TB​

TA​<TC​,TB​<TC​ and TA​=TB​

Q. According to Zeroth law of thermodynamics, if two systems $A$ and $B$ are separately in equilibrium with $C$ , then

$T_{A} = T_{B}$

$T_{A} > T_{C}, T_{B} > T_{C}$ and $T_{A} = T_{B}$

$T_{A} = T_{C}$ and $T_{A} \neq = T_{B}$

$T_{A} < T_{C}, T_{B} < T_{C}$ and $T_{A} = T_{B}$
