Calculate the rise in temperature produced.
Take the specific heat capacity of methylated spirit to be 2300 J/kg°C.
1.
"m=\\frac{Q}{c(t_2-t_1)}=0.5~kg."
2.
"c=\\frac{Q}{m(t_2-t_1)}=105~\\frac{J}{kg\\cdot \u00b0C}."
3.
"\\Delta t=\\frac{Q}{mc}=4\u00b0C."
4.
"Q=cm(t_2-t_1)=17625~J."
5.
"t_2=t_1+\\frac{Q}{cm}=56\u00b0C."
