**What is the value of CV for monatomic gas?**

The molar specific heat capacity of a gas at constant volume (Cv) is the amount of heat required to raise the temperature of 1 mol of the gas by 1 °C at the constant volume. Its value for monatomic ideal gas is 3R/2 and the value for diatomic ideal gas is 5R/2.

### Is a triatomic gas?

Triatomic gases: Molecules of these gases have three atoms and are called triatomic having atomicity equal to three. Some common example of triatomic gases is carbon dioxide, water vapour, nitrous oxide, ozone etc.

**What is the degree of freedom for Triatomic gas?**

9 degrees

**How many degrees of freedom does co2 have?**

4 degrees

#### How many degrees of freedom does oxygen have?

2 degrees

**How do you determine degrees of freedom?**

Typically, the degrees of freedom equal your sample size minus the number of parameters you need to calculate during an analysis. It is usually a positive whole number. Degrees of freedom is a combination of how much data you have and how many parameters you need to estimate.

**Why is the degree of freedom n 1?**

You end up with n – 1 degrees of freedom, where n is the sample size. Another way to say this is that the number of degrees of freedom equals the number of “observations” minus the number of required relations among the observations (e.g., the number of parameter estimates).

## What is chi square value?

A chi-square (χ2) statistic is a test that measures how a model compares to actual observed data. The data used in calculating a chi-square statistic must be random, raw, mutually exclusive, drawn from independent variables, and drawn from a large enough sample.

**What do degrees of freedom mean in statistics?**

Degrees of Freedom refers to the maximum number of logically independent values, which are values that have the freedom to vary, in the data sample. Degrees of Freedom are commonly discussed in relation to various forms of hypothesis testing in statistics, such as a Chi-Square.

**What does P value mean?**

In statistics, the p-value is the probability of obtaining results at least as extreme as the observed results of a statistical hypothesis test, assuming that the null hypothesis is correct. A smaller p-value means that there is stronger evidence in favor of the alternative hypothesis.

### How does degrees of freedom affect P value?

P-values are inherently linked to degrees of freedom; a lack of knowledge about degrees of freedom invariably leads to poor experimental design, mistaken statistical tests and awkward questions from peer reviewers or conference attendees.

**What is DF in the T table?**

The column headed DF (degrees of freedom) gives the degrees of freedom for the values in that row.

**What is critical value of T?**

A critical value is used in significance testing. It is the value that a test statistic must exceed in order for the the null hypothesis to be rejected. For example, the critical value of t (with 12 degrees of freedom using the 0.05 significance level) is 2.18.

#### What is the P value formula?

The p-value is calculated using the sampling distribution of the test statistic under the null hypothesis, the sample data, and the type of test being done (lower-tailed test, upper-tailed test, or two-sided test). an upper-tailed test is specified by: p-value = P(TS ts | H 0 is true) = 1 – cdf(ts)
