The initial temperature of the copper piece if a 240.0 gram piece of copper is dropped into 400.0 grams of water at 24.0 °C is 345.5°C
<h3>How to calculate temperature?</h3>
The initial temperature of the copper metal can be calculated using the following formula on calorimetry:
Q = mc∆T
mc∆T (water) = - mc∆T (metal)
Where;
- m = mass
- c = specific heat capacity
- ∆T = change in temperature
According to this question, a 240.0 gram piece of copper is dropped into 400.0 grams of water at 24.0 °C. If the final temperature of water is 42.0 °C, the initial temperature of the copper is as follows:
400 × 4.18 × (42°C - 24°C) = 240 × 0.39 × (T - 24°C)
30,096 = 93.6T - 2246.4
93.6T = 32342.4
T = 345.5°C
Therefore, the initial temperature of the copper piece if a 240.0 gram piece of copper is dropped into 400.0 grams of water at 24.0 °C is 345.5°C.

Reactants: H₂SO₄ + 2 NaOH
Products: 2 H₂O + Na₂SO₄
The answer is A.
Answer:
The water at 38 °C has faster-moving molecules than the sample at 295 K.
Explanation:
Converting the temperature, 295 K from Kelvin to Celsius:
295 - 273 = 22°C
⇒The boiling point of water is 100°C and its melting point 0°C
⇒When we compare water at those 2 different temperatures ( 22°C and 38°C) we can say that water is in liquid form at both these temperatures as both of them are quite below the boiling temperature and above the melting temperature.
⇒The difference in temperature between water at the 2 given temperatures = 38°C - 22°C = 16°C
Water at 38°C is at a higher temperature and so is warmer than water at a lower temperature of 22°C.
At the atomic scale, the kinetic energy of atoms and molecules is sometimes referred to as heat energy. Kinetic energy is also related to the concept of temperature. Temperature is defined as the measure of the average speed of atoms and molecules. The higher the temperature, the faster these particles of matter move.
