Use the table provided below to help solve the problem. Sam conducts an experiment to determine an unknown substance. After measuring the unknown substance on a balance, he recorded a mass of 62.5 grams. The initial temperature of the metal was 22oC and that at the end of the experiment the thermometer read 78oC for the metal. His teacher told him that the amount of heat produced was 450.1 joules. Determine the identity of the unknown metal.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
