John flies directly east for 20km, then turns to the north and flies for another 10 km before dodging a flock of geese. what’s the distance and displacement?

ok

explanation:

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
