The melting point of mercury is -39⁰C. The freezing point of alcohol is 98⁰C. How much more is the melting point of mercury when compared to the freezing point of alcohol?
Answers
The melting point of mercury is (-137⁰C) more when compared to the freezing point of alcohol.
Step-by-step explanation:
We are given that the melting point of mercury is -39⁰C. The freezing point of alcohol is 98⁰C.
We have to find how much more is the melting point of mercury when compared to the freezing point of alcohol.
As we know that when we have to compare between two numbers that how much is one number more or less as compared to another, we use addition or subtraction.
Here we will use addition as we have to find how much more is the melting point of mercury.
So, according to the question;
The melting point of mercury = The freezing point of alcohol + x
-39⁰C = 98⁰C + x
x = -98⁰C - 39⁰C
x = -137⁰C
Hence, the melting point of mercury is (-137⁰C) more when compared to the freezing point of alcohol.
Answer:
The melting point of mercury is -39⁰C. The freezing point of alcohol is 98⁰C. How much more is the melting point of mercury when compared to the freezing point of alcohol?
