Answer:
54 °C
Explanation:
Step 1: Given and required data
- Mass of water (m): 3010 g
- Heat absorbed (Q): 5.79 × 10⁵ J
- Specific heat of water (c): 4.184 J/g.°C
- Initial temperature (T₁): ?
- Final temperature (T₂): 100 °C (Boiling point of water)
Step 2: Calculate the initial temperature of water
We will use the following expression.
Q = c × m × (T₂ - T₁)
5.79 × 10⁵ J = 4.184 J/g.°C × 3010 g × (100 °C - T₁)
T₁ = 54 °C

NaCl when in solid state does not conduct electricity
while it does in aqueous solution.
Explanation:
NaCl (or what we call common salt) first needs to be either
melted or dissolved in a solution for it to conduct electricity. The reason for
this is that electrons in a solid state does not have enough freedom to move to
either the Cathode (-ve) or to the Anode (+ve). So in a liquid state the
electrons are now free enough to move.
Answer:
The answer is
<h2>0.56 km/hr </h2>
Explanation:
The speed of an object given the distance and time can be found by using the formula
From the question
distance covered by pumpkin = 3.78 km
volume = 6.8 hours
The speed is
We have the final answer as
<h3>0.56 km/hr </h3>
