一道AP【物理】题!关于物理热学HEAT的,
How much energy is required to change a 47 g
ice cube from ice at −10\x0eC to steam at 117\x0eC?
The specific heat of ice is 2090 J/kg ·
\x0e C,the
specific heat of water is 4186 J/kg ·
\x0e C,the
specific heat of stream is 2010 J/kg ·
\x0e C,the
heat of fusion is 3.33×105 J/kg,and the heat
of vaporization is 2.26 × 106 J/kg.
Answer in units of J...音符就是摄氏度的那个点

这是哪个国家的?太不严谨了
We consider the temperature is not a function of special heat and the ambient pressure is 1atm
the heat supply to ice to increase it to 0 度
Q1= C1*m*△t1=2090*0.047*10
The heat needed to change Ice to water
Q1'=3.33*10^5*0.047
The heat of increasing water the satuated water(100度）
Q2=4186*0.047*100
The heat needed to change from saturated water to saturated vapor
Q2'=2.26*10^6*0.047
Increase the vapour to superheated
Q3=2010*0.047*17
Summarize above energy

0.047*(2090*10+3.33*10^5+4186*100+2.26*10^6+2010*17)=?
你自己算算哈~~式子应该是这样的~~没看懂的话再找我~~
