Hope it helps
The ideal gas under STP is 22.4 L/mol. While the gas has a rule of P1V1/T1=P2V2/T2. So the volume under 101 kPa and 273 K is 0.2*22.4=4.48 L.
When the block of iron is placed in water the volume of water that is displaced is 27.0 cm³
<u><em> calculation</em></u>
The volume water that is displaced is equal to volume of block of the iron
volume of block of iron = length x width x height
length= 3 cm
width = 3 cm
height = 3 cm
volume is therefore = 3 cm x 3 cm x 3 cm = 27 cm³ therefore the volume displaced = 27 cm³ since the volume of water displaced is equal to volume of block.
Answer:
A. 68°F
B. 293K
Explanation:
The temperature (celsius) = 20.0°C
A. Conversion of the temperature in celsius to fahrenheit.
This is illustrated below:
°F = 9C/5 + 32
C = 20°C
°F = 9C/5 + 32
°F = 9x20/5 + 32
°F = 36 + 32
°F = 68°F
B. Temperature (Kelvin) = temperature (celsius) + 273
Temperature (celsius) = 20°C
Temperature (Kelvin) = 20°C + 273
Temperature (Kelvin) = 293K
