# Pokus - Měření účinnosti varné konvice
| č. měření | $t_1 (\degree C)$ | $t_v (\degree C)$ | $\tau (s)$ | $Q (J)$ | $P (W)$ | $n$ |

## Konvice
Značka - Bosch
$P_0=2400W$
## Hodnoty a výpočty
$m=500g$
$t_1=20.4\degree C$
$c=4180J *kg*K^{-1}$
$\tau$ … čas po který byla voda zahřívána, než se začala vařit
$Q=mc(t_v-t)$
$P=\frac{Q}\tau$
$n=\frac{P}{P_0}$
$Q=500*4180(98-20.4)$
$Q=162.184 MJ=162184000J$
$P_1=\frac{162184000}{93}=1743913,978494624$
$P_2=\frac{162184000}{96}=1689416,666666667$
$P_3=\frac{162184000}{103}=1574601,941747573$
(zbytek v excelu přes výpočty v něm)
