The ideal gas constant, R has several different values that could be used. Which quantity causes these differences?

Answer:

\boxed{\text{Pressure and volume}}

Explanation:

The measure of R is always the same, but the numbers may differ depending on the units you use.

For example, in SI units, R = 8.314 Pa·m³K⁻¹mol

If your measurement uses different units, you must either convert your units to SI or use a value of R consistent with your units.

If you use bars and litres,                       R = 0.083 14   bar·L·K⁻¹mol⁻¹.

If you use kilopascals and litres,            R = 8.314        kPa·L·K⁻¹mol

If you use atmospheres and litres,        R = 0.082 06 L·atm·K⁻¹mol⁻¹.

If you use Torr and cubic centimetres, R = 62 368     Torr·cm³ K⁻¹mol⁻¹.

The only units that don't change are "K⁻¹mol⁻¹".

\text{The quantities that affect the value of R are }\boxed{\textbf{pressure and volume}}

Say I grab a bunch of aluminum foil (9.5g) and ball it up. Aluminum has a specific heat of .9J/g*C. How much would the aluminum’
Brrunno [24]

Answer:

ΔT = 0.78 °C

Explanation:

Given data:

Mass of Al = 9.5 g

Specific heat capacity of Al = 0.9 J/g.°C

Temperature change = ?

Heat added = 67 J

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

67 J = 9.5 g × 0.9 j/g.°C × ΔT

67 J = 85.5 j/°C × ΔT

ΔT = 67 J  /  85.5 j/°C

ΔT = 0.78 °C

A block of has a length of 7cm, a width of 4cm, and a height of 10cm. Its mass measures 840g. What is it's density?
andriy [413]

Answer:

Explanation:

Density is

mass / volume = d

Mass:

840g

Volume:

7 cm x 4 cm  x 10 cm = 280 cm^3

840g / 280 cm^3 = 3 g/cm^3
