#### Answer

Phosphorus will be a $liquid$, as the temperature (56.66 $^{\circ}$C ) is higher than phosphorus's melting point of 44 $^{\circ}$C .

#### Work Step by Step

Temperature = 134 $^{\circ}$F Let Fahrenheit = $^{\circ}$F, and Celsius = $^{\circ}$C Thus, $\frac{C}{5}$ = $\frac{(F - 32)}{9}$ Thus $\frac{C}{5}$ = $\frac{(134 - 32)}{9}$ $^{\circ}$C = $\frac{(102)5}{9}$ = 56.66 $^{\circ}$C Since temperature is more than melting point of phosphorus ( 44 $^{\circ}$C ), phosphorus will be in a liquid state.
