Answer: The energy of a wave is directly proportional to its frequency, but inversely proportional to its wavelength. In other words, the greater the energy, the larger the frequency and the shorter (smaller) the wavelength.
Explanation:
You can tell them apart from its form.
If it forms loose and needs like a container to hold it up, that's liquid.
If it is hard and stable, definitely a solid.
And if you barely see something very loose (and normally goes up), that's liquid.
Answer:
Mass of the sample = m = 894.0 g
Initial temperature of the sample = T_i=-5.8^oC=267.35 KT
i
=−5.8
o
C=267.35K
Final temperature of the sample = T_f=17.5^oC=290.65 KT
f
=17.5
o
C=290.65K
Change in temperature = \Delta T=(T_f-T_i)ΔT=(T
f

)
Specific heat capacity of the substance = c
Heat required to raise the temperature of a 894.0g sample = Q
Q = 4.90kJ = 4900 J
Q=m\times c\times \Delta T=m\times c\times (T_f-T_i)Q=m×c×ΔT=m×c×(T

)
4900 J=894.0 g\times c\times (290.65 K-267.35 K)4900J=894.0g×c×(290.65K−267.35K)
c=0.23523 J/g K\approx 0.235 J/g Kc=0.23523J/gK≈0.235J/gK
The chemist will report the specific heat capacity of the substance as 0.235 J/g K.
