Mass of the shells will remain constant.
Explanation:
Sedimentary rocks are formed by the rocks that have been weathered. The microscopic shells, small pieces of rocks and mineral particles get deposited on this weathered sedimentary rocks.
The texture or chemical properties of the microscopic shell get changed. but the amount of microscopic shell deposited to make sedimentary rocks remains the same.
Chalk and coral reefs are the example of sedimentary rocks made up with microscopic shells.
The skeletal part of the shells takes part in rock formation whose mass remains unchanged although physical and chemical properties go changes.
The Thiele tube which is look like a triangle, used for the determination of melting and boiling point of the solid and liquid sample respectively. The tube consists of high viscous oil. The mouth of the triangle tube consists the thermometer and the sample through a rubber stopper. The tube is always heated in low flame as the heating mechanism of the oil is through convection current process, in which the molecules of the oil heated passes through out the bulk to make a uniform heat of the liquid. The uniform heat of the liquid is necessary to determine the exact melting point of the solid. Also the low heating rate is compulsory so that the rate of convection current be slow. The high heating rate may cause fast convection in the oil and the hot oil can spill out from the tube and may cause an accident.
570/8.5=67.0 58... you only have to take the natural part, si the answer is 67 students
Answer:
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt.
