Hello, friends rm,
in fact, just a day old here.
I need
p into MS-Word
H.C.V = (((m_w + m_e ) c_w (t_2 − t_1 ))/m_f ).
= (((2.5 + 0.39) 4.2 × 2.6)/(0.001)) kJ/kg
= (((2.89 ) × (4.2 × 2.6))/(0.001)) kJ/kg
= ((31.5588)/(0.001)) kJ/kg
= 31 558.8 kJ/kg
How do I transfer this typed formula and
calculation into microsoft word format?
Thanks!

A student seals 200g of ice−cold water in a glass vacuum
(thermos) flask and finds that it warms up by 3.5 K in one hour
SHC of water =2400 Jkg^(−1) K^(−1)
a) Calculate the average rate of heat flow in the flask in watts.
To check this result over a longer period,the student fills the flask with
equal amounts of ice and water all at 0°C, and leaves it for
4 hours. the specific latent heat(enthalpy) of fusion of ice is 0.33MJg^(−1)
b) How much ice would you expect to have melted at the end of the
four hours?
