An aluminum can weighing 10 g absorbs 106.8 J of heat and warms by 12 degrees C. What is the specific heat of the aluminum can?
Sladkaya [172]

Answer:

c_{Al} = 0.89\,\frac{J}{kg\cdot ^{\circ}C}

Explanation:

The heating process is modelled after the First Law of Thermodynamics:

Q = m \cdot c_{Al}\cdot \Delta T

The specific heat of the aluminium can is:

c_{Al} = \frac{Q}{m\cdot \Delta T}

c_{Al} = \frac{106.8\,J}{(10\,g)\cdot (12^{\circ}C)}

c_{Al} = 0.89\,\frac{J}{kg\cdot ^{\circ}C}

Chicago is about 2,800 km from Los Angeles. About how long would it take a jet plane flying 800 km/h to fly from Chicago to Los
BaLLatris [955]

<u>Answer:</u> The time taken by jet plane to reach Los Angeles from Chicago is 3.5 hours

<u>Explanation:</u>

Speed is defined as the rate at which an object moves with respect to time.

To calculate the time taken for the given speed, we use the equation:

s=\frac{d}{t}

where,

s = speed of the jet plane = 800 km/hr

d = distance traveled = 2800 km

t = time taken by jet plane = ?

Putting values in above equation, we get:

800km/hr=\frac{2800km}{t}\\\\t=\frac{2800km}{800km/hr}=3.5hr

Hence, the time taken by jet plane to reach Los Angeles from Chicago is 3.5 hours
