According to Charles's Law, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature assuming in a closed system. Mathematical equation is : V1/T1=V2/T2. 87 degrees Celsius equals 87+273.15=360.15 k, and standard temperature is 273.15 k. So, 180/360.15 = V2/273.15, V2=180*273.15/360.15 = 136.52 mL, which is the volume of gas at standard temperature.
the answer is 1345 or 5134

Answer:
A dipole-dipole force is when the positive side of a polar molecule attracts the negative side of another polar molecule.
A hydrogen bond is a dipole-dipole force and is an attraction between a slightly positive hydrogen on one molecule and a slightly negative atom on another molecule.
Answer:
The substance has a specific heat of 1.176 J/g°C
Explanation:
<u>Step 1: </u>Data given
Temperature change = 34 °C
Mass of the substance = 20 kg = 20000 grams
The substance gained 800 kJ of heat during this temperature change
<u>Step 2:</u> Calculate the specific heat
q = m*c*ΔT
⇒ with q = heat gained = 800 kJ = 800000 J
⇒ with m = the mass of the substance = 20 kg = 20000 grams
⇒ with c = the specific heat of the substance = TO BE DETERMINED
⇒ with ΔT = the change of temperature = T2 -T1 = 48° - 14 ° = 34°
c = q/(m*ΔT)
c = 800000 / (20000 * 34)
c = 1.176 J/g°C
The substance has a specific heat of 1.176 J/g°C
