What is the frequency of the sound made by a siren having a disc with 32 holes and making 25 revolution per second? ​

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

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.
