Explanation:
The relation between the speed and the de Broglie wavelength λ of a particle is
Data:
h = 6.626 × 10⁻³⁴ J·s
m = 96.0 mg
v = 30.0 m/s
Calculations:
(a) Convert milligrams to kilograms
(b) Calculate the wavelength
<span>Answer:
Q= mcâ†T
Q = energy (heat) generated or absorbed
m = mass of the substance undergoing the change in temperature
c = specific heat of the substance undergoing the change in temperature
â†T = T(final) - T(initial)
We are given:
m = (25.0 mL + 50.0 mL)*(1.00 g/mL) = 75.0 g
c = 4.18 J g^-1 °C^-1
â†T = 33.9 °C - 25.0 °C = 8.9 °C
Now we just plug those numbers in:
Q= mcâ†T
Q = (75.0 g)*(4.18 J g^-1 °C^-1)*(8.9 °C)
Q = 2790.15 J = 2.79 kJ (to three sig figs)</span>
Explanation:
boiling water has high temperature as it's molecules have high average KE ( kinetic energy) than ice....
