Calculate the kilojoules needed to heat 231 g of gold from 18 ∘C to 195 ∘C.
LuckyWell [14K]

5.27 kJ of heat are required to heat 231 g of gold from 18 °C to 195 °C.

We have 231 g of gold at 18 °C and supply it with heat to increase its temperature to 195 °C. We can calculate the amount of heat required using the following expression.

Q = c \times m \times \Delta T

where,

  • Q: heat
  • <em>c: specific heat capacity of gold</em> (0.129 J/g.°C)
  • m: mass
  • ΔT: change in the temperature

Q = \frac{0.129 J}{g.\° C}  \times 231 g \times (195 \° C - 18 \° C) = 5.27 \times 10^{3} J = 5.27 kJ

5.27 kJ of heat are required to heat 231 g of gold from 18 °C to 195 °C.

10.0 grams of water are heated during the preparation of a cup of coffee 1.0x 103 j of the heat are added to the water. which is
nirvana33 [79]

<u>Answer:</u> The final temperature of the coffee is 43.9°C

<u>Explanation:</u>

To calculate the final temperature, we use the equation:

q=mC(T_2-T_1)

where,

q = heat released = 1.0\times 10^3J=1000J

m = mass of water = 10.0 grams

C = specific heat capacity of water = 4.184 J/g°C

T_2 = final temperature = ?

T_1 = initial temperature = 20°C

Putting values in above equation, we get:

1000J=10.0g\times 4.184J/g^oC\times (T_2-20)\\\\T_2=43.9^oC

Hence, the final temperature of the coffee is 43.9°C

What distance does electromagnetic radiation travel in 33 fs?
umka2103 [35]

<u>Given:</u>

Time taken by the electromagnetic radiation, t = 33 fs

<u>To determine:</u>

The distance (d) travelled

<u>Explanation:</u>

Time taken = 33 fs (femtosecond)

1 fs = 10⁻¹⁵ s

Thus t = 33 *10⁻¹⁵ s

Speed of electromagnetic radiation = 3*10⁸ m/s

Distance = Speed * Time = 3*10⁸ ms-1 * 33*10⁻¹⁵ s = 99*10⁻⁷ m

Ans: distance traveled = 9.9*10⁻⁶ m
