7.2度=____kWh=____Ws=____J如题7.2度=____kWh=____Ws=____J如题7.2度=____kWh=____Ws=____J如题7.2度=7.2kWh=2.592×1

7.2度=____kWh=____Ws=____J如题
7.2度=____kWh=____Ws=____J
如题

7.2度=____kWh=____Ws=____J如题
7.2度= 7.2 kWh= 2.592×10^7 Ws= 2.592×10^7 J
：kWh 俗称 “度”,所以：7.2度= 7.2 kWh
7.2 kWh = 7.2kw×1 h = 7.2 ×1000 w ×3600 s = 2.592×10^7 ws = 2.592×10^7 J

7.2度=_7.2_kWh=_2.592×10^7___Ws=__2.592×10^7__J
1kWh=3.6×10^6J
度与kWh 单位相同
Ws与J 单位相同
