<h2>
Answer: 502.08 J</h2>
Explanation:
The heat (thermal energy) needed in to raise the temperature in a process can be found using the following equation:
(1)
Where:
is the heat
is the mass of the element (<u>water</u> in this case)
is the specific heat capacity of the material. In the case of water is
is the variation in temperature <u>(which is increased in this case)</u>
Knowing this, let's rewrite (1) with these values:
(2)
Finally:
Answer
Vernier caliper measure nearest to 0.01 mm.
If the correct reading of the experiment is 9.62 mm.
But you misread it and listed it as 8.62 mm.
This is Clearly the case of mistake in Accuracy.
Because the reading is wrong and answer is not accurate hence it is mistake in accuracy.
To Judge weather the reading is precise or not we should have a range where the result is acceptable but in the question no range is given. So, we cannot comment on precision.
Answer:
True
Explanation: In pulley's , length of cables doesn't change.
Answer:
The heat capacity of a sample is 37.7 J/K.
Explanation:
Given that,
Submerged temperature of tissue sample = 275 K
Mass of liquid nitrogen= 2 kg
Temperature = 70 K
Final temperature = 75 K
We need to calculate the heat
Using formula of heat
Put the value into the formula
We need to calculate the heat capacity of a sample
Using formula of heat capacity
Put the value into the formula
Hence, The heat capacity of a sample is 37.7 J/K.
