What elements combine to make and concrete?
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
Is a concrete block a pure substance or mixture?
Concrete is defined as a mixture of cement, sand, and gravel.
Is concrete a heterogenous mixture?
concrete is heterogeneous mixture. Ingredients in concrete are cement, sand, aggregates,and water. These are mixed based on mix design.
What has the greatest specific heat - granite rock - sand or water?
Water has the highest specific heat, sand and granite could be very similar but there are very many types of sand so no definite relationship can be given without more information.
Is the sand on a beach gets hot from the sun endothermic or exothermic process?
Endothermic. The sand is absorbing heat. If it was radiating heat, that would be exothermic.
Why sand gets hotter faster than water?
because water has a higher heat capacity than sand
Does sand have a high or low specific heat capacity?
sand have low specific heat capacity.
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.
Is desert sand a high or low specific heat capacity?
The desert sand has very low specific heat because it absorbs and releases heat very readily.
Which item the towel the sand or the water - has the highest specific-heat capacity?
water
Why does sand heat up more than water?
There is a material property known as heat capacity.This changes from material to material.Higher the capacity,better the heat absorbed.Since the heat capacity of sand is high,it absorbs heat so well.But for this it takes a considerable amountb of time.best heat capacity is of water.
Which item requires the least energy to increase its temperature lounge chair sand or water Explain your answer in terms of this item's specific heat?
Sand needs least energy to increase the temperature as its specific heat is very low compared to that of water. Water needs more energy to increase its temperature as its specific heat capacity is higher.
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.
Which has a greater specific heat capacity - water or sand?
Water has a greater specific heat.
Does a snail travel faster on sand or concrete?
Concrete because the sand would burn it.
What is the volume of sand in 1 cubic meter of concrete?
Concrete is a mixture of cement, sand, stone, and water. In a cuibic meter of concrete, , there is about 0.3 cubic meters of sand, or about 475 kg
Does sand absorb more heat sand or soil?
Though sand and soil have the same specific heat, sand absorbs more heat.
