Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
Question
Transcribed Image Text:A room has dimensions of 6.8 m by 6.4 m by 3.1 m. The pressure inside the room is 90,000 Pa
and the temperature is 37 °C. Another room with the same dimensions and pressure has a
temperature of -7°C. If air has a molar mass of 29
calculate the mass of air in each room in
mol
kg. Which room has the larger mass of air? Enter this value in kg rounded to the tenths place.
Question 5
Plants absorb mainly red (650 nm) and blue (450 nm) wavelengths while reflecting mostly green
This is how the chlorophyll molecule responds to EM-waves, and the reason why plants appear
green most of the time. Shown below are 3 hypothetical energy levels of the chlorophyll molecule.

difference in energy levels corresponding to blue wavelengths? C) If an electron "jumped" from
energy level 3 to energy level 1, what wavelength photon would be emitted, and D) could our eyes
detect this wavelength (use the spectrum shown below)? (650 nm = 650 x 10-9 m = 6.5 x 10-7 m)
A) 3.06
x10-19 J (Round to the hundredths place)
B) 4.42
x10-19 J (Round to the hundredths place)
nm (Round to the nearest whole number)
C)
