Answer:
mercury and alcohol
ii) used to test temperatures
The release of free energy drives the spontaneous reaction.
Spontaneity can be <span>determined
using the change in </span>Gibbs free energy
(the thermodynamic potencial):
delta G=delta H – T*delta
S
where delta H is the enthalpy and delta S is the entropy.
The direction (the sign) of delta G depends of the changes
of enthalpy and entropy. If delta G is negative then the process is
spontaneous.
In our case, both delta H and delta S are negative values, the
process as said is spontaneous which means that it may proceed in the forward
direction.
Answer:
The brightness of bulb 1 dies because it is switched off.
Here we can say that rate of flow must be constant
so here we will have
now we know that
now from above equation
so velocity will reduce by factor 0.14
