A physical change involves a change in physical properties. Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.
Answer:
(a) 17,178 mg/m3
(b) 11,625 mg/m3
Explanation:
The concentration of CO in mg/m3 can be calculated as
For standard conditions (1 atm and 25°C), P/RT is 0.0409.
Concentration of 1.5% percent by volume of CO is equivalent to 1.5*10,000 ppm= 15,000 ppm CO.
The molecular weigth of CO is 28 g/mol.
(1) For 25°C and 1 atm conditions
(b) For 200°C and 1.1 atm,
Then the concentration in mg/m3 is
Volume = mass / density
= 14.7 / 1.75
= 8.4 cm^3
<span>1. False. Intrusive rock has coarser crystal formation.
2. True. They are typically extrusive if formed by lava, intrusive through magma.
3. False. The process of lithification in sediments produces sedimentary rock.
4. True. This process compacts and cements the grains together, often squeezing out water in the process.
6. Metamorphic rock. Often rock near an igneous inclusion will metamorphose if the heat is not enough to cause melting.
7. False. All rocks in the rock cycle can become the other type with the right processes.
8. False. The rock cycle is continuous with rocks constantly shifting from one stage to another.
9. False. Foliation only occurs in metamorphic rock, with gneiss serving as a prime example.</span>
