Answer:
d = 0.98 g/L
Explanation:
Given data:
Density of acetylene = ?
Pressure = 0.910 atm
Temperature = 20°C (20+273 = 293 K)
Solution:
Formula:
PM = dRT
R = general gas constant = 0.0821 atm.L/mol.K
M = molecular mass = 26.04 g/mol
0.910 atm × 26.04 g/mol = d × 0.0821 atm.L/mol.K×293 K
23.7 atm.g/mol = d × 24.1 atm.L/mol
d = 23.7 atm.g/mol / 24.1 atm.L/mol
d = 0.98 g/L
Gamma rays
Explanation:
Every member of the electromagnetic radiation has commensurate amount of energy, wavelength and frequencies.
The electromagnetic waves with the shortest wavelengths and the highest frequencies are the gamma rays.
- Gamma rays also are the most energetic electromagnetic radiation.
- The short wavelength of gamma rays suggests that more waves passes with times.
- It's high frequency shows that a high amount of wave passes through a point at each passing of time.
- These factors combines to give its high energy. Energy of an electromagnetic radiation is a factor of its wavelength and frequency.
- Gamma rays are ionizing radiations which causes ionization of gas molecules.

Heat required in a system can be calculated by multiplying the given mass to the
specific heat capacity of the substance and the temperature difference. It is
expressed as follows:<span>
Heat = mC (T2-T1)
Heat = 10.0 g (4.18 J/g-C ) ( 6.0 C )
<span>Heat = 250.8 J</span></span>
