Types of Nuclear Radiation . Equations. Density = mass ÷ volume (D = m/v) Units: g/cm3 or g/mL. Rearranged: mass = Density x Volume Units: grams or Volume = mass ÷ density Units: cm3 or mL. Moles = mass (grams) x Molar Mass (grams / mol) . Energy = mass x (speed of light)2 E = mc2. Molar Mass = atomic mass in grams. Units: joules.
Equations given in the exam. change in thermal energy = mass × specific heat capacity × temperature change =. thermal energy for a change in state = mass × specific latent heat. =. ^ for a gas: pressure × volume = constant =.
Instead, it is important for us to notice from the equation that the following are true for a given mass of gas: When volume is constant, pressure is directly proportional to temperature. When temperature is constant, pressure is inversely proportional to volume.
A molecular formula is a simple multiple of the empirical formula showing how many of each type of atom are present in a compound. The formula of a compound can be calculated from the mass of elements in it.
change in thermal energy = mass × specific heat capacity × temperature change. ΔE = m c. Δθ. energy transferred. power = time. E. P. = t. work done. power = time. W. P. = t. useful output energy transfer. efficiency = total input energy transfer.
even a small rise in temperature brings about sufficient expansion which can be detected in the capillary of the calibrated part of the thermometer. 11. An object has a temperature of 50°F. What is the temperature in degrees Celsius and in Kelvin? Sol. 1. C = 5/9 × (F−32) Putting F=5, we get C=−15°C 2. K=5/9 × (F−32) + 273
SI Unit for mass: Kilogram. SI Unit for length: metre. SI Unit for time: second. SI Unit for current: Ampere. SI Unit for Temperature: Kelvin. SI Unit for Amount of substance: molar. Number Prefix. n (10-9) μ (10-6)
