Answer: 0.1 km
Explanation:
1) Multiply the rate (speed) by the time: 2 cm / year × 5,000 year = 10,000 cm
2) Convert cm to km, using these well know conversion factors:
1 km = 1,000 m
1 m = 100 cm
⇒ 10,000 cm × [1 m / 100 cm] × [1 km / 1,000 m] = 0.1 km
According to Gay -Lussac's law, the pressure of the can if it is heated to 1270°C is 4295.53 mm Hg.
It is defined as a gas law which states that the pressure which is exerted by the gas directly varies with its temperature and at a constant volume.The law was proposed by Joseph Gay-Lussac in the year 1808.
The pressure of the gas at constant volume reduces constantly as it is cooled till it undergoes condensation .If a graph of pressure versus temperature is plotted it is a straight line which passes through the origin .
The equation is given as, P₁/T₁=P₂/T₂
On substitution of values as ,P₁=760 mm Hg,T₁=273 K,T₂=1543 K
P₂=1543×760/273=4295.53 mm Hg.
Thus, the pressure of gas is 4295.53 mm Hg if it is heated up to 1270°C.

Answer:
The answer is C
Explanation:
Cubic metre is the metric unit for measuring volume. The cubic centimetre has a particular nomenclature called a millilitre.
The 3-dimensional space that is occupied by matter or surrounded by a surface is measured in volume, which is expressed in cubic units. A derived unit called the cubic metre serves as the SI unit of volume.
A unique designation for the cubic decimeter is the litre. To reduce the chance of confusion between the lowercase letter "ell" (l) and the number one (1), the symbol for the litre is an uppercase letter "ell". The litre cannot be represented by the script letter l (l).

Answer: 3571 L
Explanation:
According to the ideal gas equation:'
P = Pressure of the gas = 12000 Pa = 0.12 atm
V= Volume of the gas = volume of tank = ?
T= Temperature of the gas = 34°C = 307 K
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas= 17
Therefore Volume of tank is 3571 Liters.
