Which way does the heat flow?
Rus_ich [418]

No math is needed to explain this. All that you need to know is that the can (4°C) is in your hand (37°C).

Entropy will always move toward being balanced. Never will you find a lake in which half of it is 1°C and the other half is 70°C; it will be equal throughout.

Remember that "cold" doesn't exist. What we describe to be cold is actually a lack of heat.

So, by applying the two ideas above, it can be concluded that:

Since your hand is warmer than the can, the heat from your hand will be transferred to the can in order to reach an equal temperature.

element q reacts with dilute acids but not with cold water . element r does not react with dilute acids . element s displaces p
masya89 [10]

Answer:

s<p<q<r

Explanation:

Given

Element s displaces p from its oxide. Thus, s is more reactive that p

p reacts with cold water  but element q cannot react with cold water. Thus,

p is more reactive than q

Element q is able to react with weak or dilute acids but element r in unable to react with weak or dilute acids. Thus, q is more reactive that r

The order of four elements on the basis of their reactivity in descending order is as follows

s<p<q<r
