[单选题]
In order to calculate the specific ljvs 63a( qn/aoatent heat of fusion of ice, a ma 1h,ybe/eg.q-qe k3ypoqvs1) ss m of ice at a temperyh-1ey.o g/1 k) qbe, sepq3vqature of $-2^{\circ}C$ was left inside a beaker until it changed into water at $20^{\circ}C$.


If q is the energy needed to make this change for 1 kilogram of ice, the specific heat capacity of ice is $c_i$​, the specific heat capacity of water is $c_w$​, and the specific latent heat of fusion of ice is $L_F$​.
Which expression gives the specific latent heat of fusion of ice $L_F$​?

A. q−2$c_i$​−20$c_w$​
B. q−22$c_i$​
C. q−22$c-w$
D. q−$\frac{2c_i-20c_w}{m}$


参考答案:  A
