<span>4.200 calories. The formula is rise in heat (H) = the specific heat capacity (c) * rise in heat in degrees Fahrenheit (T) and volume of liquid (m) . H= cTm. Water, the typical comparison, has a specific heat capacity of 1. So to raise the Fahrenheit temperature of 105 grams of water 40 degrees, you multiply 105 * 40 * 1 = 4,200.</span>
Answer:
Particles in all states of matter are in constant motion and this is very rapid at room temperature. A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. ... Individual particles in liquids and gases have no fixed positions and move chaotically.

Answer:
Gay-Lussac's law states that pressure and temperature are directly proportional
Explanation:
Gay-Lussac's law states that pressure and temperature are directly proportional. This always occurs if the volume keeps in constant.
n and V are not directly proportional, they are the same.
At Charles Gay Lussac's law
V1 = V2
n1 = n2
T1 < T2
P1 < P2
P1 / T1 = P2 / T2
If the pressure is contant:
V1 / T1 = V2 /T2
Answer: divide by 946.353
= 1.58 x 10^-4 or 0.000159

Answer:
1
Explanation:
Using the Rydberg formula as:
where,
λ is wavelength of photon
R = Rydberg's constant (1.097 × 10⁷ m⁻¹)
Z = atomic number of atom
n₁ is the initial final level and n₂ is the final energy level
For Hydrogen atom, Z= 1
n₂ = 2
Wavelength = 410.1 nm
Also,
1 nm = 10⁻⁹ m
So,
Wavelength = 410.1 × 10⁻⁹ m
Applying in the formula as:
Solving for n₁ , we get
n₁ ≅ 1
