I believe it’s thermal, but I’m not 100 percent sure

**Answer:**

Sometimes

**Explanation:**

Sometimes meaning in occasions. If it is a "vampire star" not likely because they also cause they also make novas happen by sucking the gas from another star.

**Answer:**

The volume of the bubble near the surface will be 9.47 m³

**Explanation:**

**Given that,**

Depth = 52.0 m

Volume = 1.50 m³

Temperature at bottom = 5.5°C

Temperature at the top = 18.5°C

**We need to calculate the pressure at the depth 52.0 m**

**The pressure is **

Where, = Pressure at the surface

= Pressure at the depth

Put the value into the formula

**We need to calculate the volume of the bubble just before it reaches the surface**

**Using equation of ideal gas**

Now, The equation of at bottom and top

Put the value into the formula

**Hence, The volume of the bubble near the surface will be 9.47 m³**
