1(30%). A thin plate black body, insulated at the bottom is placed faced up in a room with wall temperatures of 30 C. Air at 0 C

ch4aika [34]

Explanation:

The given data is as follows.

Heat transfer coefficient (h) = 12 $W/m^{2}.C$

Plate temperature ( $T_{1}$ ) = $30 ^{o}C$ = 303 K

Steady state temperature ( $T_{2}$ ) = ?

Hence, formula applied for steady state is as follows.

$(h \times A \times \Delta T)_{air}$ = $\sigma \times A \times (T^{4}_{1} - T^{4}_{2})_{plate}$

Putting the given values into the above formula as follows.

$(h \times A \times \Delta T)_{air}$ = $\sigma \times A \times (T^{4}_{1} - T^{4}_{2})_{plate}$

$12 \times (T_{2} - 273)$ = $5.67 \times 10^{-8} \times [(30 + 273)^{4} - T^{4}_{2}]$

$T_{2}$ = 282.66 K

= (282.66 -273) $^{o}C$

= 9.66 $^{o}C$

Thus, we can conclude that the steady state temperature will be 9.66 $^{o}C$ .

A given atom has 3 protons, 4 neutrons, and 3 electrons. Describe how you can use those three values to describe the structure,

ELEN [110]

Charge # = protons - electons

Mass # = protons + neutrons

so that would be

3-3= charge#
3+4= mass#
