PLEASE HELP AND EXPLAIN!Calculate the energy required to heat 187.0 g of ammonia from 36.1 °C to 52.9 °C. Assume the specific he

Alenkinab [10]

Answer:

$E=1.48x10^4J$

Explanation:

Hello!

In this case, since the energy implied in a heating process is computed by using the following equation:

$E=mC(T_f-T_i)$

Whereas m is the mass, C the specific heat and T the temperature. In such a way, by plugging in the given mass, specific heat and temperatures, we obtain the following energy:

$E=187.0g*4.703\frac{J}{g\°C} (52.9\°C-36.1\°C)\\\\E=1.48x10^4J$

Considering that the specific heat can by used by unit of °C or K because their difference is equivalent.

Regards!

A ballerina weighs 103 lbs and is up on her toes with only 10.0 cm2 of her slippers in contact with the floor. What pressure is

Ahat [919]

Answer:

Explanation:

1 lb = .453 kg...so...103 x .453 = 46.72 kg

you then multiply that by the force of gravity which is 9.8(m/s2)...so...

46.72 x 9.8 = 458 newtons(kg x m/s^2), which is the force.

pressure (in pascals) = Force(N) / Area (m2)

we need to convert 10cm2 to m2 which = .001m^2

458 / .001 = 458000 = 4.58 x 10^5 Pa
