If a solid contain some particles that amount and 50°C and other particles amount mount at 110°C what must be true about the solid?

The solid is a mixture

Explanation:

Here's the complete question:

If a solid contains some particles that melt at 50°C and other particles that melt at 110°C, what must be true about the solid?

A. The solid is an element.

B. The solid is a mixture.

C. The solid is a pure substance.

D. The solid has three boiling points.

It should be noted that an element consist of an atom but in this scenario, there are different particles that also have different melting points. Therefore, it's not an element, but rather a mixture.

Also, the solid in this case is not a pure substance and doesn't have three boiling points.

Therefore, the correct option is B.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
