How much heat must be removed from 200 pounds of blanched vegetables at 189 degrees F to freeze them to a temperature of 22 degr
Virty [35]

To solve this problem it is necessary to apply the concepts related to heat exchange in the vegetable and water.

By definition the exchange of heat is given by

Q =mc\Delta T

where,

m = mass

c = specific heat

\Delta T = Change in temperature

Therefore the total heat exchange is given as

\Delta Q = Q_w+Q_v

\Delta Q = m_wc_w(T_i-T_f)+m_vc_v(T_i-T_f)

Our values are given as,

Total mass is M_T = 200lb ,however the mass of solid vegetable and water is given as,

m_v= 0.4*200lb = 80lb

m_w=0.6*200lb=120lb

T_i = 183\°F\\T_f = 22\°F\\c_w = 1Btu/lbF\\c_v = 0.24Btu/lbF

Replacing at our equation we have,

\Delta Q = m_wc_w(T_i-T_f)+m_vc_v(T_i-T_f)

\Delta Q = (120)(1)(183-22)+(80)(0.24)(183-22)

\Delta Q = 22411.2Btu

Therefore the heat removed is 22411.2 Btu

Question 2 (1 point)
Tju [1.3M]

Answer:

I know someone anwsered but it would be 400M

Explanation:

i initial velocity (u)=10m/s

acceleration (a)=0

time taken (t) =40s

then distance (s)=u t +1/2 a t^2

s= u t +0 (as a is 0)

s= 10 x 40

s= 400M

A circuit contains a 12 volt battery and two 3 ohm bulbs in series. Calculate the current
OLEGan [10]

If there are two bulbs in series, and each bulb has

                                                   resistance = 3 ohms,

then their total resistance in series is 6 ohms. 

When the series pair of bulbs is connected across the terminals
of the battery, the current through the circuit is

 Current = (voltage) / (resistance) 

               =  (12 volts) / (6 ohms)  =  2 amperes

An electric lightbulb in a lamp fixture is illuminating a small room. The system consists of the lightbulb, the lamp fixture, th
mixas84 [53]

The role of thermal energy is to balance the electrical energy lost from the light bulb.

<h3>Energy conservation</h3>

The law of energy conservation states that energy can neither be created nor destroyed but can be transformed from one form to another.

<h3>Thermal energy</h3>

This is a form of energy that occurs due to rise in temperature.

The role of thermal energy is to balance the electrical energy lost from the light bulb.
