Answer:
0.54 J/goC
Explanation:
Recall that we define the heat transferred as ;
H= mcθ
Where;
H= heat transferred = 112300J
m= mass of the metal= 240g or 0.24 Kg
c= specific heat capacity of the metal = the unknown
θ= change in temperature = (880°C-13°C) = 867°C
Substituting values and making the specific heat capacity the subject of the formula;
c= H/mθ
c= 112300/ 240×867
c= 0.54 J/goC
Hence, the specific heat capacity of the metal is 0.54 J/goC.
Explanation:
The electromagnetic spectrum shows the wavelength or frequency range of different waves starting from gamma rays to radio waves.
In the electromagnetic spectrum, gamma rays have shorter wavelength while radio wave have longest wavelength.
The correct order is as follows :
(A) Gamma rays
(B) X rays
(C) Ultraviolet
(D) Visible light
(E) Infrared waves
(F) Radio waves
So, the correct order form left to right in order of increasing wavelength is as follows :
Gamma rays < X rays < Ultraviolet < Visible Light < Infrared Waves < Radio Waves
Answer:
maltose
Explanation:
If we intend to determine the largest molecule, then we must look at the relative molecular mass of each molecule because the larger the molar mass, the larger the molecule.
Hydrogen =2 gmol-1
Carbon dioxide = 44 gmol-1
Ammonia = 17 gmol-1
Maltose= 342.3 g/mol
Hence maltose is the largest molecule among the options.
