You notice that every time you place butter on your stack of freshly made pancakes, the butter melts.
valentina_108 [34]

Answer:

Heat lost by the pancake = Heat gained by butter

Explanation:

Because energy is always conserved, this process involves the loss of energy by one substance which is gained by another.

The pancakes were freshly made, so they are hot; having the required energy to melt the butter placed on them. The butter absorbs heat from the pancakes which is equal to or greater than its melting point. Thus, the butter melts due to the heat absorbed.

Therefore,

Heat lost by the pancakes = Heat gained by butter

Can anyone explain it to me, please?

Answer:

2×10² cg

Explanation:

We'll begin by converting each of the above to the same unit of measurement.

In this case, we shall convert each of the above to kg. This can be obtained as follow:

Conversion of cg to kg

1 cg = 1×10¯⁵ Kg

Therefore,

2×10² cg = 2×10² × 1×10¯⁵

2×10² cg = 0.002 kg

Conversion of dg to Kg

1 dg = 1×10¯⁴ kg

Therefore,

10 dg = 10 × 1×10¯⁴

10 dg = 0.001 kg

Conversion of mg to kg.

1 mg = 1×10¯⁶ Kg

Therefore,

2×10² mg = 2×10² × 1×10¯⁶

2×10² mg = 0.0002 kg

Conversion of ng to kg

1 ng = 1×10¯¹² kg

Therefore,

1×10⁵ ng = 1×10⁵ × 1×10¯¹²

1×10⁵ ng = 0.0000001 Kg

Summary

1. 2×10² cg = 0.002 kg

2. 10 dg = 0.001 kg

3. 2×10² mg = 0.0002 kg

4. 0.001 kg

5. 1×10⁵ ng = 0.0000001 Kg

From the above calculation, 2×10² cg is the highest mass.

A 1.00 L sample of a gas at a pressure of 1.000atm is compressed to 0.25 L at a constanttemperature. What is the new pressure of
lord [1]

Answer:

<h3>The answer is 4 atm </h3>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new pressure

P_2 =  \frac{P_1V_1}{V_2}  \\

From the question we have

P_2 =  \frac{1 \times 1}{0.25}  =  \frac{1}{0.25}  \\

We have the final answer as

<h3>4 atm </h3>

Hope this helps you
