The right answer is indeed letter c
Answer:
Explanation:
Boyle's law states that at constant temperature:
P
PV = constant
Where: P is the pressure of a given mass of gas, and V is its volume.
The bubble wrap has a confined volume of air at constant temperature. Since a gas is easily compressible, the volume of the gas in the wrap decreases with increasing pressure. This implies that there is an inverse proportion relation between the pressure on and volume of the air.
The bubble wrap pops when stepped onto or squeezed because the pressure is high and the volume can not be compressed further. Thus, the elastic limit of the seal is exceeded. This leads to an escape of the confined air.
Answer: Region 3
Explanation: The temperature and time graph suggests that region 3 is the region in which the substance can co exist in both the phases that is solid phase and liquid phase.
Region 1 explains that the the solid has just started melting and there occurs a break point and then region 2 again explains that the solid is taking more time with temperature to get converted into the liquid and thus region 3 explains the equilibrium between the two phases.
Answer:
V2= 531.4 ml
Explanation:
T1= 273+45 °C= 318 Kelvin
T2= 273+65 °C= 338 Kelvin
V1= 500ml *( 0.001L/1ml)= 0.5 Liters
V2= = = 0.5314465409 Liters* (1 ml/0.001 L)= 531.4 ml
Answer:
2.178x10⁷kg, 2.178x10¹³mg, 2.178x10¹⁶μg, 2.178x10⁴ metric tons.
Explanation:
<em>The units are kg, μg, mg and metric tons (1metric ton = 1000kg)</em>
<em />
To solve this question we must convert, first, the grams to milligrams, and to kilograms. Then, the kilograms to metric tons and the milligrams to micrograms:
kg:
2.178x10¹⁰g * (1kg / 1000g) = 2.178x10⁷kg
mg:
2.178x10¹⁰g * (1000mg / 1g) = 2.178x10¹³mg
μg:
2.178x10¹³mg * (1000μg / 1mg) = 2.178x10¹⁶μg
metric tons:
2.178x10⁷kg * (1metric ton / 1000kg) = 2.178x10⁴ metric tons
