Specific heat refers to the heat needed to raise the temperature of the unit mass of a given substance by a given amount. The heat that is required to warm 1.20 of sand from 20.0 to 100.0 is 73 kJ.

To calculate the heat required, you need to know the specific heat capacity of sand. Assuming it is 0.83 J/g°C, you can use the formula:
Heat (J) = mass (g) x specific heat capacity (J/g°C) x change in temperature (°C)
Therefore:
Heat = 1.20 g x 0.83 J/g°C x (100.0°C - 20.0°C)
Heat = 1.20 g x 0.83 J/g°C x 80.0°C
Heat = 95.04 J

Does sand have a high or low specific heat capacity?
sand have low specific heat capacity.
Heat transferred from sand to towel to body is transferred by what?
Heat is transferred from sand to towel to body by conduction because of direct contact.
The fact that desert sand is very hot in the day and very cold at night is evidence that sand has a low specific heat capacity or high specific heat capacity?
It has a very low specific heat because it absorbs and releases heat energy very readily.
Does sand or water absorb more heat?
water
Why does the sand at the beach heat up and cool down faster than the water?
1) Sand has less specific heat, 2) It doesn't mix so easily, so the heat basically stays at the surface.
How much heat is required to warm 1.20 kg of sand from 30.0 degrees C to 100.0 degrees C?

How much cement and sand required for plastering a 1000 sq.ft length and 20 sq.ft wall of 12mm thick?
You will need about a bag of cement for this project. You will also need around 0.15 cu.m of sand.

Does sand absorb more heat sand or soil?
Though sand and soil have the same specific heat, sand absorbs more heat.
What does sand do when it is heated on a Bunsen burner?
Due to the properties of sand, when we heat it over Bunsen burner it can be used as heating buffer. The sand would absorb heat even after it is removed so we can use it similarly to a hot water bath but the sand will eventually cool down and need reheating. It is common to use this sand heat bed technique in organic laboratories or when gentle/slow heating is required.
How much heat does it take to melt sand?
There are different kinds of sand, but one of the most common, quartz sand, has a specific heat of 830 (J/kg°C)
How many bags of cement and sand required for 4500 bricks of 3 x 9?
7 bags per 1000 on mortar mix and half a truckload of "mortar" sand aught to do it.
How does sand soil rock absorb heat?
I believe its because of the color, since sand can be a brownish color, the color would absorb the heat from the sun. BUT, if the color was light, like white, it wouldn't absorb as much heat.
How much sand is required to construct 100 square feet?
The answer really requires a cubic measure - the volume - of the construction. 100 square feet can be covered to a depth of only a grain of sand or several inches (or more) of sand and, obviously, the quantity of sand required will vary accordingly.
Can calcium sand get into a bearded dragons eyes?
no calcium sand is much bigger grains than normals sand and it is easy for a reptile to digest it also retains heat
Why would sand cool faster than water in the dark?
The specific heat capacity of sand is much less than that of water. Hence sand cools earlier.
