Initial inflation of a balloon requires more pressure due to elastic rubber tension
the verdict
SUPPORTED
the evidence backs this
confidence 85/100
Initial inflation of a rubber balloon requires higher initial pressure due to the nonlinear elastic properties and stretch-induced tension of the rubber material, a phenomenon well-captured by elasticity models.
