A frozen popsicle is sitting outside in the sun. How will energy travel between the cold popsicle and the warm air around the popsicle?

When the frozen popsicle sitting outside in the Sun is exposed to warm air, energy will travel between the popsicle and the warm air as follows;

1) Convection current

Heat will be gained by the frozen popsicle by coming into contact with fresh warm air as the air flows around the popsicle while the cooling of the warm air will cause the water vapor in the air to condense and form the visible mist

In turn the popsicle will gain heat resulting in melting of the ice

2) Conduction

As the some of the mist from the air settles on the popsicle, they share their heat resulting further melting of the popsicle

3) Radiation

Radiated heat energy from the Sun is absorbed by the popsicle resulting in the melting of the popsicle

Explanation:

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
