A sample of sand initially at 22.2 °C absorbs 1364 J of heat. The final temperature of the sand is 67 °C. What is the mass (in g) of sand in the sample? The heat capacity of sand is 0.84

The mass of sand in the sample is 36.24 grams.

Explanation:

The equation used to calculate heat released or absorbed follows:

where,

q = heat absorbed = 1364 J

m = mass of sand = ?

c = heat capacity of sand = 0.84 J/g°C

= initial temperature = 22.2°C

= final temperature = 67°C

Putting values in above equation, we get:

Hence, the mass of sand in the sample is 36.24 grams.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
