How much heat is needed to raise the temperature of a 100.0g of water by 85.0 c?

Physics
1 answer:
KatRina [158]2 years ago
3 0

Answer:

35.7kJ

Explanation:

we can calculate the amount of heat energy required , using this formula

Q = mcθ

where.

Q = heat energy (Joules, J)  

m = mass of a substance (kg)  

c = specific heat capacity (units Jkg^{-1} C^{-1})

θ  = change in temperature (Celcius,C or Kelvin K)

Assume Specific heat capacity (c) of water =4200Jkg^{-1} C^{-1}

mass =0.1 kg

Q=0.1 kg*4200Jkg^{-1} C^{-1}*85C\\=35700J\\=35.7kJ

If the box weighs 40 newtons and is lifted a distance of 2 meters, how much work is done on the box?
Zarrin [17]

Answer:

The work done on the box is 80 J.

Explanation:

Given that,

Weight of box = 40 N

Distance = 2 meter

We need to calculate the work done

Using formula of work done

W=F\times x

W=mg\times x

Where, x = distance

mg = weight

Put the value into the formula

W=40\times2

W= 80\ Nm

W=80\ J

Hence, The work done on the box is 80 J.

Defined the work of vector​
cricket20 [7]

Answer:

In physics, work is the amount of energy required to perform a given task (such as moving an object from one point to another). We start by defining the scalar product of two vectors, which is an integral part of the definition of work, and then turn to defining and using the concept of work to solve problems.
